Enumerator
kParseNoFlags	No flags are set.
kParseInsituFlag	In-situ(destructive) parsing.
kParseValidateEncodingFlag	Validate encoding of JSON strings.
kParseIterativeFlag	Iterative(constant complexity in terms of function call stack size) parsing.
kParseStopWhenDoneFlag	After parsing a complete JSON root from stream, stop further processing the rest of stream. When this flag is used, parser will not generate kParseErrorDocumentRootNotSingular error.
kParseFullPrecisionFlag	Parse number in full precision (but slower).
kParseCommentsFlag	Allow one-line (//) and multi-line (/‍**/) comments.
kParseNumbersAsStringsFlag	Parse all numbers (ints/doubles) as strings.
kParseTrailingCommasFlag	Allow trailing commas at the end of objects and arrays.
kParseNanAndInfFlag	Allow parsing NaN, Inf, Infinity, -Inf and -Infinity as doubles.
kParseDefaultFlags	Default parse flags. Can be customized by defining RAPIDJSON_PARSE_DEFAULT_FLAGS.
