parse(std::istream&)

Reads a JSON value from the input stream.

Parse JSON from some file.

std::ifstream file("file.json");
jsonv::value out = parse(file);

Parameters

parse_options	Options specific to parsing the input – the indexing of source text into an AST. If unspecified, this is parse_options::create_default().
extract_options	Options specific to extraction – transforming the AST into a jsonv::value. If unspecified, this is extract_options::create_default().

Exceptions

parse_error	if the source text is invalid JSON. This is thrown for errors like unterminated strings, arrays, or stray literals. Errors of this category are described as an offset into input.
extract_error	if the AST can not be transformed into a jsonv::value. This is thrown for errors like an object with duplicate keys (note that the default jsonv::formats does not throw for this case).
