| class | parser |
Represents the result of a JSON parse: either is_valid() and the document contains a root value or parse error information is available.
Note that the document holds a strong reference to any memory allocated: any mutable copy of the input text and any memory allocated for the AST data structure. Thus, the document must not be deallocated while any value is in use.

Returns true if the document was parsed successfully. If true, call get_root() to access the document's root value. If false, call get_error_line(), get_error_column(), and get_error_message_as_cstring() to see why the parse failed.

Parses a string of JSON bytes into a document, given an allocation strategy instance. Any kind of string type is valid as long as a mutable_string_view can be constructed from it.
Valid allocation strategies are single_allocation, dynamic_allocation, and bounded_allocation.
A document is returned whether or not the parse succeeds: success state is available by calling document::is_valid().
