-## Template parameters
-
-`InputType`
-:   A compatible input, for instance:
-
-    - an `std::istream` object
-    - a `FILE` pointer
-    - a C-style array of characters
-    - a pointer to a null-terminated string of single byte characters
-    - a container `obj` for which `begin(obj)` and `end(obj)` produce a valid pair of iterators
-      (as found via ADL or member functions, with semantics compatible to `std::begin` and `std::end`)

-    - `std::default_sentinel_t`, when `IteratorType` is `std::counted_iterator`
-
-## Parameters
-
-`i` (in)
-:   an input in BON8 format convertible to an input adapter
-
-`first` (in)
-:   iterator to the start of the input
-
-`last` (in)
-:   iterator to the end of the input, or a sentinel value that compares equal to the end iterator with `operator!=`
-
-`strict` (in)
-:   whether to expect the input to be consumed until EOF (`#!cpp true` by default)
-
-`allow_exceptions` (in)
-:   whether to throw exceptions in case of a parse error (optional, `#!cpp true` by default)

-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.
-
-## 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`.

-## Member types
-
- **view_type** - the type of view returned by [`root()`](root.md) (`#!cpp basic_json_view<BasicJsonType>`)
- **value_t** - the JSON type enumeration, see [`basic_json::value_t`](../basic_json/value_t.md)
-
-## Member functions

-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.

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

-Creates an invalid (discarded) view: [`type()`](type.md) is `#!cpp value_t::discarded`,

-
-```cpp
-template<typename BasicJsonType>
-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, and
-[`materialize()`](materialize.md) to build the `BasicJsonType` value of a subtree on demand. It does not (yet) provide
-element access, iteration, `get<T>()`, JSON Pointer support, `dump()`, or comparison.
