parseAsync method

Implementation

@override

  final failPos = state.failPos;
  final errorCount = state.errorCount;
  void parse() {
    p.parseAsync(state, (result) {

          if (state.pos == state.failPos) {
            state.clearErrors(failPos, errorCount);
            state.fail<Object?>(ErrorExpectedTag(tag));
          }
        }

        onDone(null);
      }
    });
  }
