Once a value has been parsed, operations that walk it recursively -- serializing it with

[`dump`](../../api/basic_json/dump.md), hashing it, copying it, comparing two values with `#!cpp ==`, `#!cpp <`, or (in

C++20) `#!cpp <=>`, merging with [`update`](../../api/basic_json/update.md), and applying a

below that with an explicit stack instead, so none of them can exhaust the stack either, however deeply the value is

nested. Destroying a value (its destructor) never recurses at all, regardless of nesting depth, for the same reason.

[`diff`](../../api/basic_json/diff.md), [`flatten`](../../api/basic_json/flatten.md), and the binary writers
|
||||
(`to_cbor`, `to_msgpack`, ...) still recurse once per nesting level; this is called out as work in progress in the
|
||||
[assurance case](../../community/assurance_case.md#secure-design). A value deep enough to matter for these
|
||||
operations would typically first have to survive parsing without hitting a self-imposed depth limit, as described

above.

## Input size

|
||||
The library does not limit the overall size of a JSON text; a value nested or wide enough will use memory
