fastParse method

@override bool fastParse(ParseState state)

Parses input data passively, with minimal consumption of system resources during parsing.

Returns true if parsing was successful; otherwise returns false.

if(!fastParse(state)) {
  state.fail(err, state.pos);
}

Implementation

@override
bool fastParse(ParseState state) {
  final pos = state.pos;
  if (pos + 2 <= state.length) {
    final c = state.data.getUint16(pos, Endian.little);
    if (c <= _maxChar) {
      for (var i = 0; i < _cs.length; i++) {
        if (c == _cs[i]) {
          state.pos += 2;
          return true;
        }
      }
    }
  }

  return false;
}
