parse method

Implementation

@override
Result<List<O1>>? parse(State<I> state) {
  final r1 = p.parse(state);
  if (r1 == null) {
    return null;
  }

  final list = [r1.value];
  while (true) {
    final r2 = sep.fastParse(state);
    if (!r2) {
      return Result(list);
    }

    final r3 = p.parse(state);
    if (r3 == null) {
      return null;
    }

    list.add(r3.value);
  }
}
