Parse a buffer containing a complete JSON.

std::size_t
write(
    string_view s);

This function parses a complete JSON contained in the specified character buffer. The entire buffer must be consumed; if there are additional characters past the end of the complete JSON, the parse fails and an error is returned.

parser p;                                       // construct a parser
size_t n = p.write( "\[1,2,3\]" );                // parse a complete JSON
assert( n == 7 );                               // all characters consumed
value jv = p.release();                         // take ownership of the value

Linear in size.

Basic guarantee. Calls to memory_resource::allocate may throw. Upon error or exception, subsequent calls will fail until reset is called to parse a new JSON.

The number of characters consumed from the buffer.
