parse method

@override Tuple1? parse(ParseState state)

Parses input data actively and produces the result.

Returns Tuple1 of the result if parsing was successful; otherwise returns null.

final r1 = p.parse(state);

Implementation

@override
Tuple1? parse(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 null;
    }
  }

  return const Tuple1(null);
}
