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;
  for (var i = 0; i < ps.length; i++) {
    final parser = ps[i];
    if (!parser.fastParse(state)) {
      state.pos = pos;
      return false;
    }
  }

  return true;
}
