fastParse method

Implementation

@override

  if (char < 0 || char > 0x10ffff) {
    throw RangeError.range(char, 0, 0x10ffff);
  }

  final input = state.input;
  if (state.pos < input.length) {
    if (input.readChar(state.pos) == char) {
      state.pos += input.count;
      return true;
    }
  }

  state.fail<Object?>(ErrorExpectedCharacter(char));
  return false;
