Sometimes a protocol may have a JSON text followed by data that is in a different format or specification. The JSON portion can still be parsed by using the function <<ref_parser_write_some>>. Upon success, the return value will indicate the number of characters consumed from the input, which will exclude the non-JSON characters:

To use the <<ref_parser>>, declare an instance. Then call <<ref_parser_write>> once with the buffer containing representing the input JSON. Finally, call <<ref_parser_release>> to take ownership of the resulting <<ref_value>> upon success. This example persists the parser instance in a class member to reuse across calls:

The parser implementation uses temporary storage space to accumulate values during parsing. When using the <<ref_parse>> free functions, this storage is allocated and freed in each call. However, by declaring an instance of <<ref_parser>> or <<ref_stream_parser>>, this temporary storage can be reused when parsing more than one JSON text, reducing the total number of dynamic memory allocations.

Note that full precision number parsing requires the algorithm to see the full number. This means, that when used with <<ref_stream_parser>>, additional memory allocations may be necessary to store the number parts which were so far accepted by the parser. The library does try its best to avoid such allocations.

The default algorithm that the library uses to parse numbers is fast, but may result in slight precision loss. This may not be suitable for some applications, so there is an option to enable an alternative algorithm that doesn't have that flaw, but is somewhat slower. To do this, you also need to use <<ref_parse_options>> structure.

When `allow_invalid_utf16` is enabled, the parser will not throw an error in the case of illegal leading, trailing, or half a surrogate. Instead, it will replace the invalid UTF-16 code point(s) with the Unicode replacement character.

Unless otherwise specified, the parser in this library is strict. It recognizes only valid, standard JSON. The parser can be configured to allow certain non-standard extensions by filling in a <<ref_parse_options>> structure and passing it by value. By default all extensions are disabled:
