Fix CI: bind j_nested_const by reference in the json_pointer test

clang-tidy (ci_clang_tidy) flagged the new test with performance-unnecessary-copy-initialization: the local copy j_nested_const of j_nested is never modified. Bind it as a const reference instead; it still exercises the const overloads of at() and contains(). Signed-off-by: Niels Lohmann <mail@nlohmann.me>
Do not throw in contains() for an empty array reference token

-template<typename InputType>
-static bool accept(InputType&& input,
-                   const bool ignore_comments = false,
-                   const bool ignore_trailing_commas = false);
-```
-
-Checks whether the input is valid JSON, accepting and rejecting exactly what
-[`BasicJsonType::accept()`](../basic_json/accept.md) does, with the same options. Unlike [`parse()`](parse.md), this
-function never throws an exception for invalid input, and the returned `#!cpp bool` is the only result -- no document
-is returned.
-
-## Template parameters
-
-`InputType`
-:   A compatible input; see [`parse`](parse.md#template-parameters).
-
-## Parameters
-
-`input` (in)
-:   Input to check.
-
-`ignore_comments` (in)
-:   whether comments should be ignored and treated like whitespace (`#!cpp true`) or yield a parse error
-    (`#!cpp false`); (optional, `#!cpp false` by default)
-
-`ignore_trailing_commas` (in)
-:   whether trailing commas in arrays or objects should be ignored and treated like whitespace (`#!cpp true`) or
-    yield a parse error (`#!cpp false`); (optional, `#!cpp false` by default)
-
-## Return value
-
-Whether the input is valid JSON.
-
-## Exception safety
-
-Strong guarantee: this function itself never throws for an invalid input; it can only throw what allocating the
-input's own copy (for inputs that are always read into a buffer) throws.
-
-## Complexity
-
-Linear in the length of the input.

-## Examples
-
-??? example

-    ```cpp
-    --8<-- "examples/basic_json_document__accept.cpp"

-1. Creates an empty (discarded) document: [`root()`](root.md) returns a discarded view, and
-   [`is_discarded()`](is_discarded.md) is `#!cpp true`.
-2. Move constructor. Takes over `other`'s index and, if owned, its text; `other` is left as an empty document. Views
-   taken from `other` before the move remain valid, because the index is heap-allocated independently of the
-   `basic_json_document` object.
-3. `basic_json_document` is move-only. Copying is disabled because it would either duplicate a potentially large index

-```
-
-Only an **editable** document (`#!cpp Editable == true`, e.g. [`json_editable_document`](../json_editable_document.md))
-has `erase`; calling it on a read-only `basic_json_document` fails to compile (`#!cpp static_assert`).
-
-1. Removes every member of `object` whose key is `key` (see [Notes](#notes) on duplicate keys) and returns how many
-   were removed; `#!cpp 0` if `object` has no member with this key.
-2. Removes the element at index `idx` of `array`, which must already exist (`#!cpp idx < array.size()`).
-3. Removes the value the JSON pointer `ptr` refers to, relative to [`root()`](root.md), and returns how many values
-   were removed: the *parent* of the target must already exist, and the target itself is removed as in 1. (an object
-   member; `#!cpp 0` or more) or 2. (an array element; always `#!cpp 1`). `ptr` must not be empty -- [`root()`](root.md)
-   itself cannot be erased.
-
-## Template parameters
-
-`I`
-:   an integral type other than `#!cpp bool`, deduced (overloads taking a `#!cpp bool` or a non-integral type for
-    `idx` do not participate in overload resolution).
-
-## Parameters
-
-`object` (in)
-:   the object to remove a member of
-
-`array` (in)
-:   the array to remove an element of
-
-`key` (in)
-:   the key of the member(s) to remove
-
-`idx` (in)
-:   the index of the element to remove; a negative value throws (see [Exceptions](#exceptions))
-
-`ptr` (in)
-:   a JSON pointer to the value to remove, relative to `root()`
-
-## Return value
-
-1. the number of removed members (`#!cpp 0` if `object` had none with this `key`)
-2. (nothing)
-3. the number of removed values (`#!cpp 0` or more for an object member, always `#!cpp 1` for an array element)
-
-## Exceptions
-
-1. Throws [`type_error.307`](../../home/exceptions.md#jsonexceptiontype_error307) if `object` is not an object -- the
-   same message [`BasicJsonType::erase`](../basic_json/erase.md) throws for the same type.
-2. Throws `type_error.307` if `array` is not an array. Throws
-   [`out_of_range.401`](../../home/exceptions.md#jsonexceptionout_of_range401) if `idx` is negative, or if
-   `#!cpp idx >= array.size()`.
-3. Throws [`out_of_range.405`](../../home/exceptions.md#jsonexceptionout_of_range405) ("JSON pointer has no parent")
-   if `ptr` is empty. Throws what [`at`](../basic_json_view/at.md) throws (overload 3) for resolving `ptr`'s parent.
-   For the last reference token itself: if the parent is an array, throws what 2. throws for an index that is out of
-   range, or, for a token that is not a valid array index,
-   [`parse_error.106`](../../home/exceptions.md#jsonexceptionparse_error106) (a leading `#!cpp '0'`),
-   [`parse_error.109`](../../home/exceptions.md#jsonexceptionparse_error109) (not a number),
-   [`out_of_range.410`](../../home/exceptions.md#jsonexceptionout_of_range410) (too large for `size_type`), or
-   [`out_of_range.404`](../../home/exceptions.md#jsonexceptionout_of_range404) (an empty token); otherwise (an
-   object, or a primitive value the pointer's parent resolves to) throws what 1. throws.
-
-Every overload also throws [`invalid_iterator.202`](../../home/exceptions.md#jsonexceptioninvalid_iterator202) ("view
-does not belong to this document") if `object`/`array` is a [discarded](../basic_json_view/is_discarded.md) view or a
-view of a *different* document (overloads 1-2 only; overload 3 always starts from this document's own
-[`root()`](root.md)).
-
-## Complexity
-
-1. Linear in the number of members of `object`.
-2. Linear in the number of elements of `array` at or after `idx` (they move one slot over).
-3. Linear in the number of reference tokens of `ptr` and, for each token, in the number of members of the object at
-   that level or the index into the array (as [`at`](../basic_json_view/at.md)), plus the complexity of 1. or 2. for
-   the last token.
-
-## Notes
-
-!!! info "Duplicate keys"
-
-    Overload 1. removes *every* member with `key`, not just the first -- unlike [`set`](set.md), which assigns the
-    first occurrence and drops the rest. This is why it returns a count rather than a single view: there may be
-    more than one member removed, or none.
-
-Like [`set`](set.md) and [`push_back`](push_back.md), `erase` never moves an element's *value*: a view still
-referring to a removed member or element keeps showing what it last held (see [Edits](index.md#edits)) -- it just no
-longer appears when `array`/`object` is read, dumped, or iterated. Removing an element of `array` (2.) does shift the
-*links* to the elements after it, the same way `insert`, `set`, or `push_back` on the same array would; any iterator
-already taken over `array`/`object` is invalidated by an erase, since it was walking the old layout.
-
-## Examples
-
-??? example
-
-    The example below drops a deprecated field and a decommissioned entry from a configuration document -- using all
-    three overloads -- and shows what stays intact that would not with a plain `json`/`ordered_json` value: the order
-    of the fields around the ones removed, and the exact spelling of a number that was never touched.

-<small>Defined in header `<nlohmann/json_view.hpp>`</small>
-
-```cpp
-template<typename BasicJsonType, bool Editable = false>
-class basic_json_document;
-```
-
-A parsed JSON text, held as a flat index of its values
-([16 bytes per value](../../home/architecture.md#node-index-of-json-views)) instead of a tree of `BasicJsonType` values.
-Strings and numbers stay in the source text; only strings that contain escapes are decoded, into one buffer owned by
-the document. [`basic_json_view`](../basic_json_view/index.md) is a read-only handle to one value of a
-`basic_json_document`; [`materialize()`](../basic_json_view/materialize.md) turns a subtree back into the
-`BasicJsonType` value that [`BasicJsonType::parse()`](../basic_json/parse.md) would have produced for it.
-
-A document may **borrow** the text it was parsed from (the caller's buffer must then outlive the document) or **own**
-it (a copy, or an rvalue `#!cpp std::string` that was moved in); see [`owns_source`](owns_source.md). `basic_json_document`
-is move-only: copying a document would either duplicate a potentially large index and text, or leave two documents
-claiming to borrow the same buffer, so it is disabled.
-
-With `#!cpp Editable == true`, the document also offers [`set`](set.md), [`push_back`](push_back.md),
-[`insert`](insert.md), and [`erase`](erase.md) to change values in place, see [Edits](#edits) below. The source text
-itself is never written; a read-only document (`#!cpp Editable == false`, the default) does not carry any of the
-bookkeeping edits need, and calling any of them on one fails to compile (`#!cpp static_assert`).
-
-## Template parameters
-
-`BasicJsonType`
-:   a specialization of [`basic_json`](../basic_json/index.md), for instance [`json`](../json.md) or
-    [`ordered_json`](../ordered_json.md). Only 64-bit `number_integer_t`/`number_unsigned_t` types are supported; this
-    is checked with a `static_assert`.
-
-`Editable`
-:   whether the document supports [`set`](set.md), [`push_back`](push_back.md), [`insert`](insert.md), and
-    [`erase`](erase.md) (optional, `#!cpp false` by default). See [Edits](#edits) below.
-

- [**json_editable_document**](../json_editable_document.md) - editable documents of [`json`](../json.md)
- [**ordered_json_editable_document**](../ordered_json_editable_document.md) - editable documents of
-  [`ordered_json`](../ordered_json.md)

- **value_t** - the JSON type enumeration, see [`basic_json::value_t`](../basic_json/value_t.md)
-
-## Member functions
-
- [(constructor)](basic_json_document.md)
- [**parse**](parse.md) (_static_) - deserialize from a compatible input, borrowing or owning it as appropriate
- [**parse_copy**](parse_copy.md) (_static_) - deserialize a copy of a compatible input
- [**accept**](accept.md) (_static_) - check whether the input is valid JSON
- [**read**](read.md) - (re-)parse into this document, reusing its memory
- [**root**](root.md) - the view of the root value
- [**is_discarded**](is_discarded.md) - return whether the last parse failed
- [**source**](source.md) - the parsed text
- [**owns_source**](owns_source.md) - return whether the document holds its own copy of the text
- [**node_count**](node_count.md) - the number of index entries (values plus object keys)
- [**memory_usage**](memory_usage.md) - the number of bytes held by the document
- [**shrink_to_fit**](shrink_to_fit.md) - release unused index capacity
- [**set**](set.md) - replace a value, or set an object member, an array element, or the value a JSON pointer refers
-  to (`#!cpp Editable` documents only)
- [**push_back**](push_back.md) - append to an array (`#!cpp Editable` documents only)
- [**insert**](insert.md) - insert an element into an array before a given position (`#!cpp Editable` documents only)

-  (`#!cpp Editable` documents only)
-
-## Edits
-
-An editable document (`#!cpp Editable == true`) can be changed after parsing, with [`set`](set.md),
-[`push_back`](push_back.md), [`insert`](insert.md), and [`erase`](erase.md);
-[`json_editable_document`](../json_editable_document.md) and
-[`ordered_json_editable_document`](../ordered_json_editable_document.md) are the corresponding specializations. A few
-points apply to every edit:
-
- **The source text is never written**, and the parsed index never moves: every value keeps the node it was parsed
-  into, so [views](../basic_json_view/index.md) taken before an edit stay valid, including
-  [`root()`](root.md). New values (and the element sequences of an edited array/object) go to storage owned by the
-  document, allocated on demand.
- **A view keeps referring to the same value.** After [`set`](set.md) replaces the value a view refers to, that view
-  sees the new value; a view of a value that a later edit replaces or drops keeps showing what it last held. An edit
-  of an array or object, however, **invalidates the iterators taken over it** (its members may now live in a
-  different sequence), and a string obtained with [`get_string()`](../basic_json_view/get_string.md) stays valid even
-  as further edits happen (earlier buffers of edited text are kept alive, not overwritten).
- **Values are accepted three ways:** a [`basic_json_view`](../basic_json_view/index.md) of *any* document
-  (read-only or editable; it is copied, nothing is shared with the source document), a `BasicJsonType` value, or
-  anything `BasicJsonType` can be constructed from (numbers, strings, `#!cpp bool`, `#!cpp nullptr`, containers, ...).
- [`dump()`](../basic_json_view/dump.md) writes an edited document with members in document order, new members at
-  the end, and, with [`number_format::source`](../basic_json_view/number_format.md), keeps the spelling of every
-  number that was not itself edited -- see [Editing a document](../../features/json_view.md#editing-a-document) for
-  why this matters.
- [`read()`](read.md) discards all edits, [`shrink_to_fit()`](shrink_to_fit.md) does not move the node index once
-  there are edits, and [`memory_usage()`](memory_usage.md) includes the memory edits use.
-  [`source_offset()`](../basic_json_view/source_offset.md) of a value introduced by an edit is
-  `#!cpp static_cast<std::size_t>(-1)`, the same value it reports for a decoded string.

-
-```cpp

-view_type insert(view_type array, I idx, V&& value);
-```
-
-Only an **editable** document (`#!cpp Editable == true`, e.g. [`json_editable_document`](../json_editable_document.md))
-has `insert`; calling it on a read-only `basic_json_document` fails to compile (`#!cpp static_assert`).
-
-Inserts `value` into `array` as a new element before position `idx`, which must not be past the end
-(`#!cpp idx <= array.size()`; `#!cpp idx == array.size()` appends, like [`push_back`](push_back.md)). Unlike
-[`push_back`](push_back.md), a [null](../basic_json_view/is_null.md) `array` does *not* first become an empty array:
-`array` must already be an array.
-
-`value` is accepted three ways: a [`basic_json_view`](../basic_json_view/index.md) of *any* document -- read-only or
-editable, and it does not have to be `array`'s own document -- which is copied so that nothing is shared with the
-source document afterward; a `BasicJsonType` value; or anything `BasicJsonType` can be constructed from (numbers,
-strings, `#!cpp bool`, `#!cpp nullptr`, containers, ...).
-
-## Template parameters
-
-`I`
-:   an integral type other than `#!cpp bool`, deduced (overloads taking a `#!cpp bool` or a non-integral type for
-    `idx` do not participate in overload resolution).
-
-`V`
-:   the type of `value`, deduced; see above for what is accepted.
-
-## Parameters
-
-`array` (in)
-:   the array to insert into
-
-`idx` (in)
-:   the position to insert `value` before; a negative value throws (see [Exceptions](#exceptions))
-
-`value` (in)
-:   the value to insert
-
-## Return value
-
-a view of the new element, now holding `value`
-
-## Exception safety
-
-Basic exception safety: `value` is fully encoded -- including the checks below -- into storage owned by the document
-before anything already reachable from [`root()`](root.md) is touched, so a failure while encoding `value` (an
-invalid argument, or `#!cpp std::bad_alloc`) leaves the document completely unchanged, other than memory allocated
-for the encoding that is not reclaimed. A failure of a later allocation -- while `array` switches from its parsed
-layout to a growable block, or while that block grows, see [Notes](#notes) -- can still leave `array` already
-switched to that layout even though `value` itself was not inserted.
-
-## Exceptions
-
-Throws [`type_error.309`](../../home/exceptions.md#jsonexceptiontype_error309) if `array` is not an array -- the same
-message [`BasicJsonType::insert`](../basic_json/insert.md) throws for the same type; a null `array` throws this too
-(see above). Throws [`out_of_range.401`](../../home/exceptions.md#jsonexceptionout_of_range401) if `idx` is negative,
-or if `#!cpp idx > array.size()`. Throws
-[`invalid_iterator.202`](../../home/exceptions.md#jsonexceptioninvalid_iterator202) ("view does not belong to this
-document") if `array` is a [discarded](../basic_json_view/is_discarded.md) view or a view of a *different* document.
-Throws [`type_error.302`](../../home/exceptions.md#jsonexceptiontype_error302) if `value` is a
-[discarded](../basic_json_view/is_discarded.md) view or a [discarded](../basic_json/is_discarded.md) `BasicJsonType`
-value, and [`type_error.319`](../../home/exceptions.md#jsonexceptiontype_error319) if `value` is (or contains) a
-binary value -- `BasicJsonType` can hold one, but a `json_document` cannot. Throws
-[`type_error.316`](../../home/exceptions.md#jsonexceptiontype_error316) if `value` is (or contains) a string that is
-not valid UTF-8, with the same message [`BasicJsonType::dump()`](../basic_json/dump.md) gives for that string.
-
-## Complexity
-
-Linear in the number of elements of `array` at or after `idx` (they move one slot over), plus time linear in the
-size of `value` to encode it into the document's storage (constant for a scalar, linear in the number of nested
-values for an array or object): like [`push_back`](push_back.md), the elements of `array` move to a growable block
-of links the first time it is inserted into (or [`set`](set.md)/[`push_back`](push_back.md) on), and that block
-grows in amortized constant time; inserting before the end within that block still shifts every later element.
-
-## Notes
-
-Like [`set`](set.md) on a member or an element, `insert` never moves an existing *element's value* -- only where
-`array`'s *links* to its elements live -- so a view of an existing element of `array` stays valid across an
-`insert`, and keeps referring to the same element even though its index shifts. Any iterator already taken over
-`array` is invalidated, since it was walking the old layout. See [Edits](index.md#edits) for what stays valid across
-an edit in general.
-
-## Examples
-
-??? example
-
-    The example below inserts a step into the middle of a deployment plan, without touching the steps that come
-    after it, and shows that a view taken before the insert keeps referring to the same element even though its

-
-1. Deserialize from a compatible input, borrowing or owning it depending on its value category and type (see Notes).
-2. Deserialize from a pair of input iterators.
-
-Both overloads accept exactly what [`BasicJsonType::parse()`](../basic_json/parse.md) accepts, with the same
-`ignore_comments`/`ignore_trailing_commas` options, but build a [`basic_json_document`](index.md) (a flat index into
-the input) instead of a tree of `BasicJsonType` values.
-
-## Template parameters
-
-`InputType`
-:   A compatible input, for instance:
-
-    - a `#!cpp std::string`, `#!cpp std::string_view`, or a C-style array of characters
-    - a pointer to a null-terminated string of single byte characters
-    - a container for which `#!cpp obj.data()` and `#!cpp obj.size()` give contiguous single-byte access, e.g.
-      `#!cpp std::vector<char>` or `#!cpp std::vector<std::uint8_t>`
-    - an `#!cpp std::istream` object, or anything else [`BasicJsonType::parse()`](../basic_json/parse.md) accepts
-
-`IteratorType`
-:   a compatible iterator type, for instance a pair of pointers such as `ptr` and `ptr + len`, or a pair of
-    `#!cpp std::string::iterator`
-
-## Parameters
-
-`input` (in)
-:   Input to parse from.
-
-`allow_exceptions` (in)
-:   whether to throw exceptions in case of a parse error (optional, `#!cpp true` by default)
-
-`ignore_comments` (in)
-:   whether comments should be ignored and treated like whitespace (`#!cpp true`) or yield a parse error
-    (`#!cpp false`); (optional, `#!cpp false` by default)
-
-`ignore_trailing_commas` (in)
-:   whether trailing commas in arrays or objects should be ignored and treated like whitespace (`#!cpp true`) or
-    yield a parse error (`#!cpp false`); (optional, `#!cpp false` by default)
-
-`first` (in)
-:   iterator to the start of a character range
-
-`last` (in)
-:   iterator to the end of a character range
-
-## Return value
-
-The parsed document. If `allow_exceptions` is `#!cpp false` and the input is not valid JSON, the returned document is
-discarded; see [`is_discarded`](is_discarded.md).
-
-## Exceptions
-
-Throws the same exception [`BasicJsonType::parse()`](../basic_json/parse.md) throws for the same input and options --
-the same exception id, message, and position -- because on a failing input the library's own parser is run on the
-same bytes to produce the diagnostic. Additionally throws
-[`out_of_range.416`](../../home/exceptions.md#jsonexceptionout_of_range416) if the input is 4 GiB or larger, a size
-[`BasicJsonType::parse()`](../basic_json/parse.md) does not reject.
-
-## Complexity
-
-Linear in the length of the input.
-
-## Notes
-
-**Ownership.** Whether the document borrows `input` or owns a copy of it depends on its value category and type:
-
-| `input`                                                                             | ownership                                                    |
-|--------------------------------------------------------------------------------------|--------------------------------------------------------------|
-| lvalue byte container (`std::string`, `std::vector<char>`, ...), `std::string_view`, C string, character array | **borrowed** -- `input` must outlive the document |
-| rvalue `#!cpp std::string`                                                            | **owned**, moved in without a copy                            |
-| rvalue byte container other than `#!cpp std::string`                                  | **owned**, copied                                             |
-| stream, wide string, or anything else read through the general input adapter          | **owned**, read into a buffer (a stream is read to its end)   |
-
-For overload (2), a pair of pointers to single-byte integers (e.g. `#!cpp const char*`, `#!cpp std::uint8_t*`) is
-borrowed. From C++20 on, so is any other contiguous iterator over single bytes, such as
-`#!cpp std::vector<char>::iterator` or `#!cpp std::string::const_iterator`. Before C++20 these iterators cannot be
-told apart from other class-type iterators, so their range is read into an owned buffer, as is any non-contiguous
-range (e.g. of a `#!cpp std::list<char>`).
-
-See [`owns_source`](owns_source.md) to check which happened after a call, and the
-[feature page](../../features/json_view.md) for the reasoning.
-
-**Numbers.** As for [`BasicJsonType::parse()`](../basic_json/parse.md), an integer literal too large for the 64-bit
-integer type becomes a floating-point value.

-`parse_copy()` accepts and rejects exactly what [`parse()`](parse.md) does, and classifies numbers the same way; it

-# <small>nlohmann::basic_json_document::</small>push_back
-
-```cpp
-template<typename V>
-view_type push_back(view_type array, V&& value);
-```
-
-Appends `value` as a new last element of `array`. A [null](../basic_json_view/is_null.md) `array` first becomes an
-empty array, the same way [`set`](set.md) turns a null `object` into an empty object.
-
-`value` is accepted three ways: a [`basic_json_view`](../basic_json_view/index.md) of *any* document -- read-only or
-editable, and it does not have to be `array`'s own document -- which is copied so that nothing is shared with the
-source document afterward; a `BasicJsonType` value; or anything `BasicJsonType` can be constructed from (numbers,
-strings, `#!cpp bool`, `#!cpp nullptr`, containers, ...).
-
-Only an **editable** document (`#!cpp Editable == true`, e.g. [`json_editable_document`](../json_editable_document.md))
-has `push_back`; calling it on a read-only `basic_json_document` fails to compile (`#!cpp static_assert`).
-
-## Template parameters
-
-`V`
-:   the type of `value`, deduced; see above for what is accepted.
-
-## Parameters
-
-`array` (in)
-:   the array (or null value) to append to
-
-`value` (in)
-:   the value to append
-
-## Return value
-
-a view of the new last element of `array`, now holding `value`
-
-## Exception safety
-
-Basic exception safety: `value` is fully encoded -- including the checks below -- into storage owned by the document
-before anything already reachable from [`root()`](root.md) is touched, so a failure while encoding `value` (an
-invalid argument, or `#!cpp std::bad_alloc`) leaves the document completely unchanged, other than memory allocated
-for the encoding that is not reclaimed. A failure of a later allocation -- while `array` switches from its parsed
-layout to a growable block, or while that block grows, see [Notes](#notes) -- can still leave a partial effect, such
-as a null `array` argument already turned into an empty array even though `value` itself was not appended.
-
-## Exceptions
-
-Throws [`type_error.308`](../../home/exceptions.md#jsonexceptiontype_error308) if `array` is neither an array nor
-null -- the same message [`BasicJsonType::push_back`](../basic_json/push_back.md) throws for the same type. Throws
-[`invalid_iterator.202`](../../home/exceptions.md#jsonexceptioninvalid_iterator202) ("view does not belong to this
-document") if `array` is a [discarded](../basic_json_view/is_discarded.md) view or a view of a *different* document.
-Throws [`type_error.302`](../../home/exceptions.md#jsonexceptiontype_error302) if `value` is a
-[discarded](../basic_json_view/is_discarded.md) view or a [discarded](../basic_json/is_discarded.md) `BasicJsonType`
-value, and [`type_error.319`](../../home/exceptions.md#jsonexceptiontype_error319) if `value` is (or contains) a
-binary value -- `BasicJsonType` can hold one, but a `json_document` cannot. Throws
-[`type_error.316`](../../home/exceptions.md#jsonexceptiontype_error316) if `value` is (or contains) a string that is
-not valid UTF-8, with the same message [`BasicJsonType::dump()`](../basic_json/dump.md) gives for that string.
-
-## Complexity
-
-Amortized constant, plus time linear in the size of `value` to encode it into the document's storage (constant for
-a scalar, linear in the number of nested values for an array or object): the elements of `array` move to a growable
-block of links the first time it is appended to (or [`set`](set.md) on), and that block itself grows -- doubling its
-capacity, so the cost of growing it amortizes to constant per element -- only once it runs out of room. See
-[Notes](#notes).
-
-## Notes
-
-Like [`set`](set.md) on a member or an element, `push_back` never moves an existing element itself -- only where
-`array`'s *links* to its elements live -- so a view of an existing element of `array` stays valid across a
-`push_back`, but any iterator already taken over `array` is invalidated, since it was walking the old layout. See
-[Edits](index.md#edits) for what stays valid across an edit in general.
-
-## Examples
-
-??? example
-
-    The example below appends records to an array one at a time, as they might arrive from a stream of events,
-    without ever building a `BasicJsonType` value for the array or for the records already in it, and shows that a
-    view taken from an earlier `push_back` still refers to the same element once later ones have run.

-   key -- the first one, should the key occur more than once, and the later duplicates are then dropped (see the
-   [Notes](#notes) below) -- or appends a new member at the end otherwise. A [null](../basic_json_view/is_null.md)
-   `object` first becomes an empty object.
-3. Assigns `value` to the element at index `idx` of the array `array`, which must already exist (`#!cpp idx <
-   array.size()`).
-4. Sets the value the JSON pointer `ptr` refers to, relative to [`root()`](root.md), to `value`. The *parent* of the
-   target must already exist: an object member is set as in 2. (added if it does not exist yet), an array element is
-   assigned as in 3., and a last reference token of `#!cpp "-"`, or equal to the size of the array, appends `value`
-   instead, exactly as [`push_back`](push_back.md) would. An empty `ptr` sets [`root()`](root.md) itself, as in 1.
-
-In every overload, `value` is accepted three ways: a [`basic_json_view`](../basic_json_view/index.md) of *any*
-document -- read-only or editable, and it does not have to be `target`'s/`object`'s/`array`'s own document -- which
-is copied so that nothing is shared with the source document afterward; a `BasicJsonType` value; or anything
-`BasicJsonType` can be constructed from (numbers, strings, `#!cpp bool`, `#!cpp nullptr`, containers, ...).
-
-## Template parameters
-
-`V`
-:   the type of `value`, deduced; see above for what is accepted.
-
-`I`
-:   an integral type other than `#!cpp bool`, deduced (overloads taking a `#!cpp bool` or a non-integral type for
-    `idx` do not participate in overload resolution).
-
-## Parameters
-
-`target` (in)
-:   the value to replace
-
-`object` (in)
-:   the object (or null value) whose member to set
-
-`array` (in)
-:   the array whose element to assign
-
-`key` (in)
-:   the key of the member to set
-
-`idx` (in)
-:   the index of the element to assign; a negative value throws (see [Exceptions](#exceptions))
-
-`ptr` (in)
-:   a JSON pointer to the value to set, relative to `root()`
-
-`value` (in)
-:   the new value
-
-## Return value
-
-1. a view of `target`, now holding `value`
-2. a view of the member `key` of `object`, now holding `value`
-3. a view of the element `idx` of `array`, now holding `value`
-4. a view of the value `ptr` refers to, now holding `value`
-
-## Exception safety
-
-Basic exception safety: `value` is fully encoded -- including the checks below -- into storage owned by the document
-before anything already reachable from [`root()`](root.md) is touched, so a failure while encoding `value` (an
-invalid argument, or `#!cpp std::bad_alloc`) leaves the document completely unchanged, other than memory allocated
-for the encoding that is not reclaimed. A failure of a later allocation -- while an edited array or object switches
-from its parsed layout to a growable block, see [Notes](#notes) -- can still leave a partial effect, such as a
-[null](../basic_json_view/is_null.md) `object`/`array` argument already turned into an empty object/array even
-though `value` itself was not linked in.
-
-## Exceptions
-
-1. Throws [`type_error.302`](../../home/exceptions.md#jsonexceptiontype_error302) if `value` is a
-   [discarded](../basic_json_view/is_discarded.md) view, or a [discarded](../basic_json/is_discarded.md)
-   `BasicJsonType` value (e.g. `#!cpp BasicJsonType(value_t::discarded)`) -- an object or array `value`, of either
-   kind, is fine and is encoded as a whole subtree.
-2. Throws [`type_error.305`](../../home/exceptions.md#jsonexceptiontype_error305) if `object` is neither an object
-   nor null -- the same message [`operator[]`](../basic_json_view/operator%5B%5D.md) throws for a string argument on
-   such a value. Throws [`type_error.316`](../../home/exceptions.md#jsonexceptiontype_error316) if `key` is not
-   valid UTF-8, with the same message [`BasicJsonType::dump()`](../basic_json/dump.md) gives for that string.
-   Also throws what 1. throws for `value`.
-3. Throws `type_error.305` if `array` is not an array -- the same message `operator[]` throws for a numeric argument
-   on such a value. Throws [`out_of_range.401`](../../home/exceptions.md#jsonexceptionout_of_range401) if `idx` is
-   negative, or if `#!cpp idx >= array.size()`. Also throws what 1. throws for `value`.
-4. Throws what [`at`](../basic_json_view/at.md) throws (overload 3) for resolving `ptr`'s parent, except that a
-   missing object member or an array index equal to the array's size at the very last reference token is not an
-   error there (it becomes a new member or an appended element) instead of
-   [`out_of_range.403`](../../home/exceptions.md#jsonexceptionout_of_range403)/[`out_of_range.402`](../../home/exceptions.md#jsonexceptionout_of_range402).
-   For the last reference token itself: if the parent is an object (or a primitive value, where it throws
-   `type_error.305`), throws what 2. throws; if the parent is an array, throws what 3. throws for an index that is
-   out of range, or, for a token that is not a valid array index,
-   [`parse_error.106`](../../home/exceptions.md#jsonexceptionparse_error106) (a leading `#!cpp '0'`),
-   [`parse_error.109`](../../home/exceptions.md#jsonexceptionparse_error109) (not a number),
-   [`out_of_range.410`](../../home/exceptions.md#jsonexceptionout_of_range410) (too large for `size_type`), or
-   [`out_of_range.404`](../../home/exceptions.md#jsonexceptionout_of_range404) (an empty token). Also throws what 1.
-   throws for `value`.
-
-Every overload also throws [`type_error.319`](../../home/exceptions.md#jsonexceptiontype_error319) if `value` is (or
-contains) a binary value -- `BasicJsonType` can hold one, but a `json_document` cannot -- and
-[`invalid_iterator.202`](../../home/exceptions.md#jsonexceptioninvalid_iterator202) ("view does not belong to this
-document") if `target`/`object`/`array` is a [discarded](../basic_json_view/is_discarded.md) view or a view of a
-*different* document (overloads 1-3 only; overload 4 always starts from this document's own [`root()`](root.md)).
-
-## Complexity
-
-1. Linear in the size of `value` (encoding it into the document's storage): constant for a scalar, linear in the
-   number of nested values for an array or object. If `target` is itself an array or object that spans more than one
-   node in its parent's original, unedited layout, and `value` is a scalar, replacing it additionally costs time
-   linear in the number of elements of that parent, the *first* time -- see [Notes](#notes).
-2. Linear in the number of members of `object`, to find an existing member with `key`, plus the complexity of 1. for
-   `value`.
-3. Constant, plus the complexity of 1. for `value`.
-4. Linear in the number of reference tokens of `ptr` and, for each token, in the number of members of the object at
-   that level or the index into the array (as [`at`](../basic_json_view/at.md)), plus the complexity of 2. or 3. for
-   the last token.
-
-## Notes
-
-!!! info "Duplicate keys"
-
-    If `object` already has more than one member with `key` (2.), the *first* one is assigned `value` and every
-    later member with the same key is removed -- so that a lookup, an iteration, and
-    [`materialize()`](../basic_json_view/materialize.md) of `object` afterward all agree on a single value for
-    `key`, the same way [`operator[]`](../basic_json_view/operator%5B%5D.md) already picks the first occurrence of a
-    duplicate key for reading. See the [Notes on duplicate keys](../basic_json_view/operator%5B%5D.md#notes) of
-    `operator[]`.
-
-Setting a member (2.) or an element (3., through 4.) of an array or object whose elements have not been edited
-before switches it from its parsed layout to a growable block holding links to its elements; a later
-[`push_back`](push_back.md) or `set` on the same container reuses that block, growing it (amortized constant time)
-only once it runs out of room. This never moves an element itself -- only where the container's *links* to its
-elements live -- so a view of an element stays valid, but any iterator already taken over the container is
-invalidated, since it was walking the old layout. See [Edits](index.md#edits) for what stays valid across an edit in
-general.
-
-The same switch happens, for the same reason, when overload 1. replaces a multi-node array/object value with a
-scalar: the *parent's* element sequence is what has to switch to links, not `target` itself, because the parent
-originally stepped over `target`'s whole subtree by its node count, which no longer applies once `target` is a
-one-node scalar.
-
-## Examples
-
-??? example "Example: (1)/(2)/(3)/(4) replace a value, set a member, assign an element, set via a JSON pointer"
-
-    The example below edits a small configuration document -- replacing a value, adding an object member, assigning
-    an array element, and reaching a field through a JSON pointer -- and shows what
-    [`dump()`](../basic_json_view/dump.md) preserves that is lost once the same edits are made on a `BasicJsonType`
-    value instead: the order object members were written in, and the exact spelling of a number that was never
-    touched.

-!!! warning "Invalidates views"
-
-    Unlike moving the document, `shrink_to_fit()` **invalidates every view taken from this document before the

-This is unlike `#!cpp std::vector::shrink_to_fit()`, which promises nothing about validity but in practice often

-## Exceptions
-
-1. The function can throw the following exceptions, both with the same message as the corresponding call to
-   [`BasicJsonType::at`](../basic_json/at.md):
-    - Throws [`type_error.304`](../../home/exceptions.md#jsonexceptiontype_error304) if the value is not an object.
-    - Throws [`out_of_range.403`](../../home/exceptions.md#jsonexceptionout_of_range403) if no member has key `key`.
-2. The function can throw the following exceptions, both with the same message as the corresponding call to
-   [`BasicJsonType::at`](../basic_json/at.md):
-    - Throws [`type_error.304`](../../home/exceptions.md#jsonexceptiontype_error304) if the value is not an array.
-    - Throws [`out_of_range.401`](../../home/exceptions.md#jsonexceptionout_of_range401) if `#!cpp idx >= size()`.
-3. The function can throw the following exceptions, all with the same message as the corresponding call to
-   [`BasicJsonType::at`](../basic_json/at.md):
-    - Throws [`parse_error.106`](../../home/exceptions.md#jsonexceptionparse_error106) if an array index in `ptr`
-      begins with `#!cpp '0'`.
-    - Throws [`parse_error.109`](../../home/exceptions.md#jsonexceptionparse_error109) if an array index in `ptr` is
-      not a number.
-    - Throws [`out_of_range.401`](../../home/exceptions.md#jsonexceptionout_of_range401) if an array index in `ptr`
-      is out of range.
-    - Throws [`out_of_range.402`](../../home/exceptions.md#jsonexceptionout_of_range402) if a reference token is
-      `#!cpp "-"` at an array -- `at` never inserts an element, so `#!cpp "-"` is always invalid.
-    - Throws [`out_of_range.403`](../../home/exceptions.md#jsonexceptionout_of_range403) if a reference token names
-      an object member that does not exist.
-    - Throws [`out_of_range.404`](../../home/exceptions.md#jsonexceptionout_of_range404) if `ptr` cannot be resolved
-      because a reference token is used on a primitive value.
-
-None of these exceptions carry a [`JSON_DIAGNOSTICS`](../macros/json_diagnostics.md) path: the view has no
-`BasicJsonType` value to point at, so the exception is created without one, even if `BasicJsonType` was built with
-`JSON_DIAGNOSTICS` enabled.
-
-## Complexity
-
-1. Linear in the number of members: as for [`ordered_json`](../ordered_json.md), members are compared one after
-   another, in document order, stopping at the first match. Each comparison first checks the key's length --
-   already known from the index, without reading the key bytes -- before comparing its content.
-   Objects with 128 or more members get a hash index while parsing, so that a lookup in them takes constant time
-   on average.
-2. Linear in `idx`: elements are skipped one at a time from the first one, since they are not a fixed size in the
-   index (unlike `BasicJsonType`'s array, which is random-access).
-3. Linear in the number of reference tokens of `ptr` and, for each token, in the number of members of the object at
-   that level (as 1.) or the index into the array (as 2.).
-
-## Notes
-
-Unlike [`operator[]`](operator[].md), which returns a [discarded](is_discarded.md) view for a missing key or an
-out-of-range index, `at` always throws -- exactly as `BasicJsonType::at` does, and with the same messages, so
-existing error handling written against `BasicJsonType::at` keeps working unchanged when switched to a view. This
-also holds for overload 3: unlike [`operator[]`](operator[].md) with a JSON pointer, which returns a discarded view
-for a missing key or an out-of-range index, `at` throws for those too (`out_of_range.403`/`out_of_range.401`).

-## Notes
-
-For an object, iteration visits **every** member, including all occurrences of a duplicate key -- unlike
-[`operator[]`](operator[].md), [`at`](at.md), [`find`](find.md), [`contains`](contains.md), and [`count`](count.md),
-which all resolve to the *first* member with a given key. See the
-[Notes on duplicate keys](operator[].md#notes) of `operator[]`.
-
-Because objects are iterated in document order rather than sorted by key, the order seen here can differ from what
-iterating the [`materialize()`](materialize.md)d `BasicJsonType` value would produce: a `#!cpp basic_json` object
-(`std::map`-backed by default) sorts its keys, while a view does not.
-
-## Examples

-2. Checks whether a JSON pointer `ptr` can be resolved, starting at this value.
-
-## Parameters
-
-`key` (in)
-:   key value to check its existence
-
-`ptr` (in)
-:   JSON pointer to check its existence
-
-## Return value
-
-1. `#!cpp true` if the value is an object and has a member with key `key`, `#!cpp false` otherwise

-
-## Exception safety

-
-1. Linear in the number of members: as for [`ordered_json`](../ordered_json.md), members are compared one after

-
-    If `#!cpp v.contains(key)` returns `#!cpp true`, then `#!cpp v[key]` is not [discarded](is_discarded.md). If

-    throw.
-
-!!! info "Overload 2 never throws"
-
-    Unlike [`BasicJsonType::contains(const json_pointer&)`](../basic_json/contains.md), which can throw for certain
-    malformed pointers (for instance an empty array-index reference token), overload 2 never throws: a missing key,
-    an out-of-range or malformed array index, a `#!cpp "-"` index, or a reference token used on a primitive all
-    simply make it return `#!cpp false`.
-
-## Examples
-
-??? example "Example: (1) check with key"

-    The example below counts how many of a batch of records carry an optional `retry_of` field, using `contains()`

-```
-
-Serializes this value (and its subtree) directly from the flat index, without ever building a `BasicJsonType` value
-first. With the default `#!cpp numbers == number_format::shortest`, the result is the same string
-[`BasicJsonType::dump`](../basic_json/dump.md) would produce for the value
-[`BasicJsonType::parse()`](../basic_json/parse.md) builds from the same source text, called with the same `indent`,
-`indent_char`, and `ensure_ascii` -- except that members of an object appear in document order rather than sorted by
-key, and *every* occurrence of a repeated key is written rather than only the last one (see
-[Notes on duplicate keys](operator[].md#notes)). For a `json_view` (whose `BasicJsonType` is not ordered), this means
-`dump()` can print an object's members in a different order than [`materialize()`](materialize.md)`.dump()` of the
-same subtree.
-
-## Parameters
-
-`indent` (in)
-:   If `indent` is nonnegative, array elements and object members are pretty-printed with that indent level. An
-    indent level of `0` only inserts newlines. `-1` (the default) selects the most compact representation.
-
-`indent_char` (in)
-:   The character used for indentation if `indent` is greater than `0`. The default is ` ` (space).
-
-`ensure_ascii` (in)
-:   If `ensure_ascii` is `#!cpp true`, all non-ASCII characters in the output are escaped with `\uXXXX` sequences, and
-    the result consists of ASCII characters only.
-
-`numbers` (in)
-:   how to write numbers, see [`number_format`](number_format.md): `shortest` (the default) writes them the way
-    [`BasicJsonType::dump`](../basic_json/dump.md) would; `source` copies every number exactly as it appears in the
-    source text.
-
-## Return value
-
-string containing the serialization of this value, or `#!cpp "<discarded>"` if the view is
-[discarded](is_discarded.md).
-
-## Exception safety
-
-Strong exception safety: if an exception is thrown, there are no changes to the view or the document it refers to.
-
-## Exceptions
-
-May throw `#!cpp std::bad_alloc` if allocating the output string fails. Unlike
-[`BasicJsonType::dump`](../basic_json/dump.md), there is no `error_handler` parameter and no
-[`type_error.316`](../../home/exceptions.md#jsonexceptiontype_error316): the view only ever holds text the parser
-already validated as UTF-8, so there is nothing to replace or ignore.
-
-## Complexity
-
-Linear in the size of the output text.
-
-## Notes
-
-The walk over the subtree is iterative, so the nesting depth it can write is limited by available memory only, not by
-the call stack -- as for [`materialize()`](materialize.md).
-
-Strings are escaped by the same rules as [`BasicJsonType::dump`](../basic_json/dump.md). With
-`#!cpp numbers == number_format::shortest`, floats are written with the library's shortest round-trip conversion,
-exactly as [`BasicJsonType::dump`](../basic_json/dump.md) would (e.g. `#!cpp 1.5`, `#!cpp 100.0`, `#!cpp 1e+100`), and
-integers are copied from the source text -- already canonical in JSON, so this matches their shortest form too --
-except that `#!cpp -0` is written as `#!cpp 0`, the way [`BasicJsonType::parse()`](../basic_json/parse.md) reads it.
-`#!cpp number_format::source` copies every number exactly as written in the source text instead, with no exception
-for `#!cpp -0` -- `#!cpp 1.50`, `#!cpp 1E2`, `#!cpp -0.0`, `#!cpp -0`, or all digits of an integer literal with more
-digits than any number type holds (such a literal is itself classified as a float, see
-[What is different](../../features/json_view.md#what-is-different)) -- something `BasicJsonType` cannot do, since
-parsing already reduces every number to its parsed value.

-## Examples

-    without ever building a `BasicJsonType` value for the surrounding array or for the parts of it that were not

-# <small>nlohmann::basic_json_view::</small>get
-
-```cpp
-template<typename T>
-T get() const;
-```
-
-Converts the value to `T`.
-
-For the types below, the conversion works directly on the flat index -- no `BasicJsonType` value is built for it:
-
- `#!cpp bool`
- arithmetic types other than `#!cpp bool` (from a number; from a boolean, as `#!cpp 0`/`#!cpp 1`, exactly as
-  [`BasicJsonType::get<T>()`](../basic_json/get.md) converts a boolean)
- `#!cpp std::nullptr_t`
- `#!cpp std::basic_string<char, Traits, Alloc>` (including `string_t`) -- a copy of the string
- [`string_view_t`](index.md#member-types) -- **no copy**: the returned view points into the document's
-  [`source()`](../basic_json_document/source.md) text, or, for a string that contains escape sequences, into the
-  document's own buffer of decoded strings (see [`get_string()`](get_string.md))
- `BasicJsonType` -- equivalent to [`materialize()`](materialize.md)
- `basic_json_view` -- returns `#!cpp *this`
- `#!cpp std::vector<U, A>` -- element by element, each converted with `#!cpp get<U>()`; `#!cpp
-  std::vector<basic_json_view>` keeps a view of every element instead of a value
- `#!cpp std::map<K, V, C, A>` and `#!cpp std::unordered_map<K, V, H, E, A>`, if `K` is constructible from a `#!cpp
-  (const char*, std::size_t)` pair -- member by member, each value converted with `#!cpp get<V>()`; with a repeated
-  key, the *last* value is kept, as [`BasicJsonType::parse()`](../basic_json/parse.md) (and
-  [`materialize()`](materialize.md)) does; `#!cpp std::map<std::string, basic_json_view>` keeps views of the members
-  instead of values
-
-Every other `T` -- `#!cpp std::list`, `#!cpp std::pair`, `#!cpp std::array`, enumerations, user types with a
-`from_json()`, ... -- is converted by `#!cpp materialize().get<T>()`: the subtree is built into a real `BasicJsonType`
-value first (as [`BasicJsonType::parse()`](../basic_json/parse.md) would), and converted from there exactly as
-[`BasicJsonType::get<T>()`](../basic_json/get.md) would convert it.
-
-## Template parameters
-
-`T`
-:   the type to convert the value to
-
-## Return value
-
-the value, converted to `T`
-
-## Exception safety
-
-Strong exception safety: if an exception is thrown, there are no changes to the view or the document it refers to.
-
-## Exceptions
-
- For the directly-converted types listed above (other than `BasicJsonType` and `basic_json_view`, which never
-  throw): throws [`type_error.302`](../../home/exceptions.md#jsonexceptiontype_error302) if the value's type does not
-  match `T` -- the same exception, with the same message, that [`BasicJsonType::get<T>()`](../basic_json/get.md)
-  throws for the same JSON type and `T`.
- For `#!cpp std::vector<U, A>`: throws `type_error.302` if the value is not an array; otherwise, whatever converting
-  an element to `U` throws.
- For `#!cpp std::map`/`#!cpp std::unordered_map`: throws `type_error.302` if the value is not an object; otherwise,
-  whatever converting a member to the mapped type throws.
- For every other `T`: whatever [`materialize().get<T>()`](../basic_json/get.md) throws -- typically `type_error.302`,
-  or whatever a user-provided `from_json()` throws.
-
-None of the exceptions thrown directly by this function (the first three bullets above) carry a
-[`JSON_DIAGNOSTICS`](../macros/json_diagnostics.md) path: the view has no `BasicJsonType` value to point at. An
-exception thrown while converting through `materialize()` (the last bullet) is different: it is thrown by a real
-`BasicJsonType` value, so it **does** carry a `JSON_DIAGNOSTICS` path if `BasicJsonType` was built with it enabled.
-
-## Complexity
-
- `#!cpp bool`, arithmetic types, `#!cpp std::nullptr_t`, [`string_view_t`](index.md#member-types), `basic_json_view`:
-  constant.
- `#!cpp std::basic_string<char, Traits, Alloc>`: constant, plus one allocation and a copy of the string's bytes.
- `BasicJsonType`: linear in the size of the subtree, see [`materialize()`](materialize.md).
- `#!cpp std::vector<U, A>`: linear in the number of elements, times the complexity of converting one element to `U`.
- `#!cpp std::map`/`#!cpp std::unordered_map`: linear in the number of members for walking them, plus the container's
-  own insertion cost per member (logarithmic for `#!cpp std::map`, amortized constant for `#!cpp
-  std::unordered_map`), times the complexity of converting one member to the mapped type.
- every other `T`: linear in the size of the subtree (building the `BasicJsonType` value), plus the complexity of
-  [`BasicJsonType::get<T>()`](../basic_json/get.md) on it.
-
-## Notes
-
-!!! info "Floating-point values"
-
-    A floating-point `T` is converted from the same digits the lexer would see during `#!cpp BasicJsonType::parse()`,
-    using the same conversion, so the result is bit-for-bit identical to `#!cpp BasicJsonType::parse(text).get<T>()`
-    for the same source text.
-
-!!! info "Duplicate keys"
-
-    `#!cpp std::map`/`#!cpp std::unordered_map` conversions keep the *last* value of a repeated key, like
-    [`materialize()`](materialize.md) and [`BasicJsonType::parse()`](../basic_json/parse.md) do. This is the opposite
-    of [`operator[]`](operator[].md)/[`at`](at.md)/[`find`](find.md)/[`contains`](contains.md), which resolve to the
-    *first* occurrence (see the [Notes on duplicate keys](operator[].md#notes)).
-
-!!! info "No pointers, references, or implicit conversion"
-
-    Unlike `BasicJsonType`, `basic_json_view` has no stored value anywhere to hand out a pointer or a reference to, so
-    it provides neither `#!cpp get_ptr()`, `#!cpp get_ref()`, nor `#!cpp operator ValueType()`.
-    [`get_string()`](get_string.md) (equivalently, `#!cpp get<string_view_t>()`) is the zero-copy alternative for
-    strings.
-
-## Examples
-
-??? example
-
-    The example below reads typed fields straight into C++ variables, collects a view of every array element with
-    `#!cpp get<std::vector<basic_json_view>>()` instead of a value, and converts a nested object into a user type
-    through its `from_json()` -- which runs on a `BasicJsonType` value `materialize()` builds for just that one
-    member.
-
-    ```cpp
-    --8<-- "examples/basic_json_view__get.cpp"
-    ```
-
-    Output:

-# <small>nlohmann::basic_json_view::</small>get_string

-```cpp

-
-Returns the string value as a [`string_view_t`](index.md#member-types), without copying it.
-
-## Return value
-
-The string, as a [`string_view_t`](index.md#member-types) that points either into the document's

-had to be decoded once when the document was parsed).
-
-## Exception safety
-
-Strong exception safety: if an exception is thrown, there are no changes to the view or the document it refers to.
-
-## Exceptions
-
-Throws [`type_error.302`](../../home/exceptions.md#jsonexceptiontype_error302) if the value is not a string; example:
-`"type must be string, but is array"`.
-
-This exception does not carry a [`JSON_DIAGNOSTICS`](../macros/json_diagnostics.md) path: the view has no
-`BasicJsonType` value to point at, so the exception is created without one, even if `BasicJsonType` was built with
-`JSON_DIAGNOSTICS` enabled.
-
-## Complexity
-
-Constant.
-
-## Notes
-
-`basic_json_view` has no `BasicJsonType` value stored anywhere, so unlike `BasicJsonType`, it has no `get_ref()` to
-hand out a reference to a stored `string_t`. `get_string()` (equivalently, [`get<string_view_t>()`](get.md)) is the
-zero-copy alternative: [`BasicJsonType::get_ref<const string_t&>()`](../basic_json/get_ref.md) is its closest
-counterpart, except that it returns a view instead of a reference to a value that must already exist.
-
-The returned [`string_view_t`](index.md#member-types) is valid exactly as long as the view that produced it -- see the
-[validity rules](index.md) of `basic_json_view` -- and, for a string with no escapes, for as long as the document's
-source text.
-
-## Examples
-
-??? example
-
-    The example below pulls one field out of a JSON text that stands in for a large API response, and shows that no
-    `#!cpp std::string` was allocated for it: the returned view still points inside the original buffer. A field that
-    contains an escape sequence cannot point into the original text -- it was decoded once into the document's own
-    buffer instead -- but still avoids a per-field allocation.

-
-<small>Defined in header `<nlohmann/json_view.hpp>`</small>
-
-```cpp
-template<typename BasicJsonType, bool Editable = false>
-class basic_json_view;
-```
-
-A read-only handle to one value of a [`basic_json_document`](../basic_json_document/index.md): two pointers (a pointer
-to the document and a pointer into its index), trivially copyable. A view is valid as long as
-
- the document is alive,
- the document has not been re-parsed with [`read()`](../basic_json_document/read.md) (or
-  [`parse()`](../basic_json_document/parse.md) into it) or shrunk with
-  [`shrink_to_fit()`](../basic_json_document/shrink_to_fit.md) since the view was taken, and
- if the document borrows its source text, that text is still alive.
-
-Moving the document itself does not invalidate its views: the index is heap-allocated independently of the
-`basic_json_document` object.
-
-`basic_json_view` provides the read-only part of the `BasicJsonType` interface: the type-inspection functions, element
-access, lookup, iteration, conversion, and comparison -- [`get<T>()`](get.md), [`get_string()`](get_string.md),
-[`number_token()`](number_token.md), and [`materialize()`](materialize.md) to build the `BasicJsonType` value of a
-subtree on demand. [`operator[]`](operator%5B%5D.md), [`at`](at.md), [`contains`](contains.md), and
-[`value`](value.md) also accept a [`json_pointer`](../json_pointer/index.md). [`operator==`](operator_eq.md) and
-[`operator!=`](operator_ne.md) compare two views, or a view and a `BasicJsonType` value, without ever building a
-`BasicJsonType` value for a view; no ordering comparison (`#!cpp operator<`) is provided.
-
-`basic_json_view` itself is always read-only -- it never has a `set` or `push_back` of its own. A view of an
-**editable** document (`#!cpp Editable == true`) sees every edit made through
-[`basic_json_document::set`](../basic_json_document/set.md) and
-[`basic_json_document::push_back`](../basic_json_document/push_back.md): once a value is changed, every view that
-still refers to it -- including ones taken before the change -- reads the new value. See
-[Edits](../basic_json_document/index.md#edits).
-
-## Template parameters
-
-`BasicJsonType`
-:   a specialization of [`basic_json`](../basic_json/index.md), matching the
-    [`basic_json_document`](../basic_json_document/index.md) the view was taken from.
-
-`Editable`
-:   whether the view is of an editable document, matching the [`basic_json_document`](../basic_json_document/index.md)
-    it was taken from (optional, `#!cpp false` by default). See [Edits](../basic_json_document/index.md#edits).

- **size_type** - `#!cpp std::size_t`
- **string_view_t** - `#!cpp std::string_view` on C++17 and newer, a minimal internal substitute otherwise
- **iterator**, **const_iterator** - a forward iterator over the elements of an array or the member values of an
-  object, in document order; both names refer to the same type, since a view is always read-only

-# <small>nlohmann::basic_json_view::</small>items

-```cpp
-/* unspecified */ items() const noexcept;
-```
-
-Returns a range of [`item`](index.md#member-types) values -- (key, value) pairs -- for use in range-based for loops.
-The key of an array element is its index, converted to a string, as for
-[`BasicJsonType::items()`](../basic_json/items.md).
-
-The returned type is not part of the public API and may change between versions; use a range-based for loop (see the
-example), or `#!cpp decltype(v.items())` if you need to name it.
-
-```cpp
-for (const auto& item : v.items())
-{
-    std::cout << "key: " << item.key() << ", value: " << item.value() << '\n';

-{
-    std::cout << "key: " << key << ", value: " << value << '\n';

-Note the `#!cpp const auto` (by value), not `#!cpp const auto&`: unlike `BasicJsonType::items()`, whose elements are

-is nothing for a reference to bind to.
-
-## Return value
-
-A range whose iterators dereference to [`item`](index.md#member-types) and whose `#!cpp begin()`/`#!cpp end()` are
-equivalent to [`basic_json_view::begin()`](begin.md)/[`end()`](end.md), in document order.

-## Notes
-
-As for [`begin()`](begin.md)/[`end()`](end.md), `items()` visits **every** member of an object, including all
-occurrences of a duplicate key -- unlike [`operator[]`](operator[].md), [`at`](at.md), [`find`](find.md),
-[`contains`](contains.md), and [`count`](count.md), which resolve to the *first* member with a given key. See the
-[Notes on duplicate keys](operator[].md#notes) of `operator[]`.
-
-!!! danger "Lifetime issues"
-
-    As for `BasicJsonType::items()`, calling `items()` on a temporary view (or a temporary document) is dangerous:
-    the range refers back to the document, so the document must outlive the loop. See
-    [#2040](https://github.com/nlohmann/json/issues/2040) for the `BasicJsonType` background.
-
-## Examples
-
-??? example
-
-    The example below shows a settings object whose source text records every update to a key as a duplicate
-    member, in the order they happened. `items()` walks all of them, so the update history is visible, while
-    [`operator[]`](operator[].md) only ever sees the *first* one and [`materialize()`](materialize.md) -- like

-## Notes

-`materialize()` replays the subtree through the same SAX builder [`BasicJsonType::parse()`](../basic_json/parse.md)

-would be; the JSON nesting depth is limited only by available memory, as for `BasicJsonType::parse()` itself.
-
-Unlike parsing with [`JSON_DIAGNOSTIC_POSITIONS`](../macros/json_diagnostic_positions.md) enabled, the values
-produced by `materialize()` do not carry source positions: there is no lexer run during the replay to record them.

-Calling `materialize()` on the same view repeatedly builds a new, independent `BasicJsonType` value each time; it
-never caches the result.

-Strong exception safety: if an exception is thrown, there are no changes to the view or the document it refers to.
-
-## Exceptions
-
-Throws [`type_error.302`](../../home/exceptions.md#jsonexceptiontype_error302) if the value is not a number; example:
-`"type must be number, but is string"`.
-
-This exception does not carry a [`JSON_DIAGNOSTICS`](../macros/json_diagnostics.md) path: the view has no
-`BasicJsonType` value to point at, so the exception is created without one, even if `BasicJsonType` was built with
-`JSON_DIAGNOSTICS` enabled.
-
-## Complexity
-
-Constant.
-
-## Notes
-
-`BasicJsonType` has no counterpart to this function: once a number is parsed into `number_integer_t`,
-`number_unsigned_t`, or `number_float_t`, its original textual form (leading zeros aside, which are already rejected
-by the grammar; trailing zeros in the fraction; the case and sign of the exponent; ...) is gone. `number_token()` is
-useful precisely where that form must survive -- a price or an identifier that must be reproduced exactly, or a
-number too large for any of `BasicJsonType`'s number types to hold without loss.
-
-The returned [`string_view_t`](index.md#member-types) always points into the document's
-[`source()`](../basic_json_document/source.md) text -- numbers are never decoded into the document's separate string
-buffer -- and is valid exactly as long as that text is, see the [validity rules](index.md) of `basic_json_view`.

-## Examples
-
-??? example
-
-    The example below keeps a price and an order ID exactly as they were written in an incoming order, where
-    converting them with [`get<T>()`](get.md) would lose information: the price picks up floating-point rounding, and

-# <small>nlohmann::basic_json_view::</small>operator[]
-
-```cpp
-// (1)
-basic_json_view operator[](string_view_t key) const;
-basic_json_view operator[](const char* key) const;
-basic_json_view operator[](const string_t& key) const;
-

-```
-
-1. Returns the value of the object member with key `key` -- the first one, should the key occur more than once (see
-   the [Notes](#notes) below) -- or a [discarded](is_discarded.md) view if there is no such member.
-2. Returns the array element at index `idx`, or a [discarded](is_discarded.md) view if `idx` is out of range. (The
-   `#!cpp int` overload only exists so that an integer literal is not ambiguous between this overload and 1.)
-3. Returns the value a JSON pointer `ptr` refers to, starting at this value, or a [discarded](is_discarded.md) view
-   wherever resolving it further is not possible without inserting into or extending the document (see
-   [Return value](#return-value) and [Exceptions](#exceptions) below).
-
-## Parameters
-
-`key` (in)
-:   object key of the element to access
-
-`idx` (in)
-:   index of the element to access
-
-`ptr` (in)
-:   JSON pointer to the element to access
-
-## Return value
-
-1. the value of the first member with key `key`, or a discarded view if `#!cpp is_object()` is `#!cpp false` or no
-   member has this key
-2. the element at index `idx`, or a discarded view if `#!cpp is_array()` is `#!cpp false` or `#!cpp idx >= size()`
-3. the value `ptr` resolves to, starting at this value, or a discarded view for exactly the reference tokens where the
-   **const** overload of [`BasicJsonType::operator[]`](../basic_json/operator%5B%5D.md) invokes undefined behavior for
-   the same pointer and the same document: an object member that does not exist, or an array index that is out of
-   range
-
-## Exception safety
-
-Strong exception safety: if an exception is thrown, there are no changes to the view or the document it refers to.
-
-## Exceptions
-
-1. Throws [`type_error.305`](../../home/exceptions.md#jsonexceptiontype_error305) if the value is not an object --
-   the same exception, with the same message, that the **const** overload of
-   [`BasicJsonType::operator[]`](../basic_json/operator%5B%5D.md) throws for a string argument on a non-object value.
-2. Throws [`type_error.305`](../../home/exceptions.md#jsonexceptiontype_error305) if the value is not an array --
-   the same exception, with the same message, that the **const** overload of
-   [`BasicJsonType::operator[]`](../basic_json/operator%5B%5D.md) throws for a numeric argument on a non-array value.
-3. Throws the same exceptions, with the same messages, that the **const** overload of
-   [`BasicJsonType::operator[]`](../basic_json/operator%5B%5D.md) throws for the same pointer and the same document:
-    - [`out_of_range.402`](../../home/exceptions.md#jsonexceptionout_of_range402) if a reference token is `#!cpp "-"`
-      at an array.
-    - [`out_of_range.404`](../../home/exceptions.md#jsonexceptionout_of_range404) if a reference token cannot be
-      resolved because it is used on a primitive value.
-    - [`parse_error.106`](../../home/exceptions.md#jsonexceptionparse_error106) if an array index in `ptr` begins
-      with `#!cpp '0'`.
-    - [`parse_error.109`](../../home/exceptions.md#jsonexceptionparse_error109) if an array index in `ptr` is not a
-      number.
-
-None of these exceptions carry a [`JSON_DIAGNOSTICS`](../macros/json_diagnostics.md) path: the view has no
-`BasicJsonType` value to point at, so the exception is created without one, even if `BasicJsonType` was built with
-`JSON_DIAGNOSTICS` enabled.
-
-## Complexity
-
-1. Linear in the number of members: as for [`ordered_json`](../ordered_json.md), members are compared one after
-   another, in document order, stopping at the first match. Each comparison first checks the key's length --
-   already known from the index, without reading the key bytes -- before comparing its content, so a key of a
-   different length than `key` is rejected without touching the source text.
-   Objects with 128 or more members get a hash index while parsing, so that a lookup in them takes constant time
-   on average.
-2. Linear in `idx`: elements are skipped one at a time from the first one, since they are not a fixed size in the
-   index (unlike `BasicJsonType`'s array, which is random-access).
-3. Linear in the number of reference tokens of `ptr` and, for each token, in the number of members of the object at
-   that level (as 1.) or the index into the array (as 2.).
-
-## Notes
-
-Unlike `BasicJsonType::operator[]`, which is undefined behavior (guarded by a
-[runtime assertion](../../features/assertions.md)) for a missing key on a **const** value, this operator always
-returns a safe, testable result: a [discarded](is_discarded.md) view, which is `#!cpp false` in a boolean context.
-There is also no non-const overload that inserts a missing key or extends an array -- a view never modifies the
-document.
-
-!!! info "Duplicate keys"
-
-    If the source text has an object with a duplicate key, `#!cpp operator[]` (and [`at`](at.md), [`find`](find.md),
-    [`contains`](contains.md), [`count`](count.md)) all resolve to the *first* member with that key, because a
-    lookup can stop as soon as it finds a match. This is different from
-    [`materialize()`](materialize.md) (and [`BasicJsonType::parse()`](../basic_json/parse.md)), which replay every
-    member in order and so end up keeping the *last* value for a repeated key -- there is no reason for them to stop
-    early. [`begin()`](begin.md)/[`end()`](end.md) and [`items()`](items.md) iterate over *all* members, including
-    duplicates, in document order. See the example below and [`size()`](size.md#notes).
-
-!!! info "JSON pointer resolution"
-
-    Overload 3 walks `ptr` one reference token at a time, starting at this value, the same way [`at`](at.md) and
-    [`contains`](contains.md) do. It only ever returns a discarded view where the **const** overload of
-    `BasicJsonType::operator[]` would be undefined behavior for the same pointer -- a missing object member or an
-    out-of-range array index -- and still throws for every other way `ptr` can fail to resolve. See
-    [`at`](at.md#exceptions) for the checked version, which throws in every case instead, and
-    [`contains`](contains.md) for a version that never throws.
-
-## Examples
-
-??? example "Example: (1)/(2) access specified element"
-
-    The example below reads a couple of fields out of a batch of user records without ever materializing a full
-    `BasicJsonType` value for the batch. `operator[]` is used both to look up an optional object member and to index
-    into an array -- in both cases, a missing value comes back as a discarded view that can be tested with a plain
-    `#!cpp if`, instead of relying on undefined behavior.
-
-    ```cpp
-    --8<-- "examples/basic_json_view__operator[].cpp"
-    ```
-
-    Output:
-
-    ```json
-    --8<-- "examples/basic_json_view__operator[].output"
-    ```
-
-??? example "Example: (3) access specified element via JSON pointer"
-
-    The example below reaches straight into one deeply nested field of a large document with a single JSON pointer,
-    without ever building a tree for the rest of it, and shows the discarded-view and throwing outcomes of a pointer
-    that cannot be fully resolved.
-
-    ```cpp
-    --8<-- "examples/basic_json_view__operator[]_json_pointer.cpp"

-# <small>nlohmann::basic_json_view::</small>operator bool
-
-```cpp
-explicit operator bool() const noexcept;
-```
-
-Returns whether this view refers to a value, i.e. the negation of [`is_discarded()`](is_discarded.md). Being
-`#!cpp explicit`, this conversion is only considered in a boolean context (`#!cpp if (v)`, `#!cpp !v`, `#!cpp v &&

-
-```cpp
-// (1)
-bool operator==(const basic_json_view& lhs, const basic_json_view& rhs);
-
-// (2)
-bool operator==(const basic_json_view& lhs, const BasicJsonType& rhs);
-bool operator==(const BasicJsonType& lhs, const basic_json_view& rhs);
-```
-
-1. Compares two views for equality: whether the values [`BasicJsonType::parse()`](../basic_json/parse.md) would
-   produce for `lhs` and `rhs` are equal, according to `BasicJsonType`'s [`operator==`](../basic_json/operator_eq.md).
-2. Compares a view and a `BasicJsonType` value for equality, in either order: whether the value `parse()` would
-   produce for the view and the other operand are equal, according to `BasicJsonType`'s
-   [`operator==`](../basic_json/operator_eq.md).
-
-Neither overload builds a `BasicJsonType` value for a view to do the comparison (see [Notes](#notes) below). Numbers
-compare by value across their types (`#!cpp 1 == 1.0`), and an object compares by its members, with duplicate keys
-resolved exactly as `parse()` resolves them -- the last value, at the position of the first occurrence of the key.
-
-## Parameters
-
-`lhs` (in)
-:   first value to consider
-
-`rhs` (in)
-:   second value to consider
-
-## Return value
-
-whether the values `lhs` and `rhs` are equal
-
-## Exception safety
-
-Strong exception safety: if an exception is thrown, there are no changes to either operand, or to the document(s) a
-view refers to.
-
-## Exceptions
-
-May throw `#!cpp std::bad_alloc`. Unlike the other comparison and most other `basic_json_view` functions,
-`operator==` is not `#!cpp noexcept`: resolving an object's members needs a temporary array to sort them by key (see
-[Complexity](#complexity) below), and that allocation can fail.
-
-## Complexity
-
-Linear in the size of the compared values: every number, string, array element, and object member is visited at most
-once, and the walk is iterative, so the nesting depth it can compare is limited by available memory only, not by the
-call stack (as for [`materialize()`](materialize.md)). Resolving an object's members takes an additional O(n log n)
-in the number of members at that level, since they are sorted by key to detect and resolve duplicates before being
-compared. Two arrays of different [`size()`](size.md) are rejected without visiting either one's elements.
-
-## Notes
-
-Only a single number, boolean, or `#!cpp null` value is ever materialized into a `BasicJsonType`, to reuse its
-`operator==` -- for numbers, so that values written differently in the source text but equal in value (e.g. an
-integer and a floating-point literal) still compare equal, following the same rules `BasicJsonType` does for special
-values such as `#!cpp NaN`. Constructing one of these scalars never allocates. Strings are compared directly, without
-allocating, either from the source text on both sides or, for overload 2, against `BasicJsonType`'s own string.
-Arrays and objects are never materialized at all; only their elements or members are visited, one pair at a time.
-
-!!! info "How objects are compared"
-
-    For a [`json_view`](../json_view.md) (`BasicJsonType::object_t` is `#!cpp std::map`), members are compared by
-    key, regardless of the order they appear in the source text. For an
-    [`ordered_json_view`](../ordered_json_view.md) (`object_t` is `ordered_map`), they are compared in the order
-    they occur, so the very same two objects with their members reordered can compare equal as `json_view`s but not
-    as `ordered_json_view`s. This is exactly how [`json`](../json.md) and [`ordered_json`](../ordered_json.md)
-    compare, see ["Comparing different `basic_json` specializations"](../basic_json/operator_eq.md#notes).
-
-!!! info "Discarded views"
-
-    A [discarded](is_discarded.md) view compares the same way a discarded `BasicJsonType` value does, which is
-    governed by
-    [`JSON_USE_LEGACY_DISCARDED_VALUE_COMPARISON`](../macros/json_use_legacy_discarded_value_comparison.md): by
-    default, a discarded view is never equal to anything, not even another discarded view.
-
-No ordering comparison (`#!cpp operator<`) is provided for `basic_json_view`; [`materialize()`](materialize.md) is
-the way to get a `BasicJsonType` value that supports it.
-
-## Examples
-
-??? example
-
-    The example below checks whether a newly received configuration differs from the previous one, and whether a
-    received document matches what a test expects -- directly on views, without ever materializing a `BasicJsonType`
-    value for either side.
-
-    ```cpp
-    --8<-- "examples/basic_json_view__operator_eq.cpp"

-# <small>nlohmann::basic_json_view::</small>operator<<
-
-```cpp
-std::ostream& operator<<(std::ostream& o, const basic_json_view& v);
-```
-
-Not available when [`JSON_NO_IO`](../macros/json_no_io.md) is defined.
-
-Serializes the given view `v` to the output stream `o`, using [`dump`](dump.md) -- exactly as
-`#!cpp operator<<(std::ostream&, const basic_json&)` does for a `basic_json` value.
-
- The indentation of the output can be controlled with the member variable `width` of the output stream `o`. For
-  instance, using the manipulator `std::setw(4)` on `o` sets the indentation level to `4`, and the serialization
-  result is the same as calling `#!cpp v.dump(4)`. A `width` of `0` or less (the default) selects the most compact
-  representation, as `#!cpp v.dump(-1)` does.
- The indentation character can be controlled with the member variable `fill` of the output stream `o`. For instance,
-  the manipulator `std::setfill('\t')` sets indentation to use a tab character rather than the default space
-  character.
- As for `basic_json`, `o`'s `width` is reset to `0` after this call, whether or not it was greater than `0` before.
-
-Numbers are always written as `#!cpp v.dump()` writes them by default, i.e. as with
-[`number_format::shortest`](number_format.md); there is no way to select `#!cpp number_format::source` through the
-stream.

-
-## Exceptions
-
-May throw `#!cpp std::bad_alloc`, propagated from [`dump`](dump.md#exceptions). Unlike
-`#!cpp operator<<(std::ostream&, const basic_json&)`, there is no UTF-8 decoding step that could throw
-[`type_error.316`](../../home/exceptions.md#jsonexceptiontype_error316), and no `error_handler` to choose between --
