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;
  if (p1.fastParse(state)) {
    if (p2.fastParse(state)) {
      if (p3.fastParse(state)) {
        if (p4.fastParse(state)) {
          if (p5.fastParse(state)) {
            return const Tuple1(null);
          }
        }
      }
    }
  }

  state.pos = pos;
}
