Description:

RapidJSON is a fast JSON parser and generator for C++. It was inspired
by RapidXml.

RapidJSON is small but complete. It supports both SAX and DOM style
API. The SAX parser is only a half thousand lines of code.

RapidJSON is fast. Its performance can be comparable to strlen(). It
also optionally supports SSE2/SSE4.1 for acceleration.

RapidJSON is self-contained. It does not depend on external libraries
such as BOOST. It even does not depend on STL.

RapidJSON is memory friendly. Each JSON value occupies exactly 16/20
bytes for most 32/64-bit machines (excluding text string). By default
it uses a fast memory allocator, and the parser allocates memory
compactly during parsing.

RapidJSON is Unicode friendly. It supports UTF-8, UTF-16, UTF-32 (LE &
BE), and their detection, validation and transcoding internally. For
example, you can read a UTF-8 file and let RapidJSON transcode the
JSON strings into UTF-16 in the DOM. It also supports surrogates and
"\u0000" (null character).

JSON(JavaScript Object Notation) is a light-weight data exchange
format. RapidJSON should be in fully compliance with RFC4627/ECMA-404.
