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;
  final r1 = p.fastParse(state);
  state.pos = pos;
  if (r1) {
    return const Tuple1(null);
  }
}
