To use the <<ref_stream_parser>>, declare an instance. Then call <<ref_stream_parser_write>> zero or more times with successive buffers representing the input JSON. When there are no more buffers, call <<ref_stream_parser_finish>>. The function <<ref_stream_parser_done>> returns `true` after a successful call to `write` or `finish` if parsing is complete.

The <<ref_stream_parser>> implements a https://en.wikipedia.org/wiki/Online_algorithm[__streaming algorithm__]; it allows incremental processing of large JSON inputs using one or more contiguous character buffers. The entire input JSON does not need to be loaded into memory at once. A network server can use the streaming interface to process incoming JSON in fixed-size amounts, providing these benefits:

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:

Upon success, the return value will indicate the number of characters consumed from the input, which will exclude the non-JSON characters:有时，某个协议可能在 JSON 文本之后跟随采用不同格式或规范的数据。此时仍可使用函数 &lt;<ref_parser_write_some>&gt; 来解析 JSON 部分。成功时，其返回值将指示从输入中消耗的字符数，该数量不包括非 JSON 的字符：</ref_parser_write_some>

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.
