parseOn method

  1. @override
Result<R> parseOn(
  1. Context context
)
override

Parses the given context.

Overridden in concrete subclasses to implement the parser-specific logic. Takes a parse context and returns the resulting context, which is either a Success or Failure context.

Implementation

@override
Result<R> parseOn(Context context) {
  final beforeContext = before.parseOn(context);
  if (beforeContext is Failure) return beforeContext;
  final resultContext = delegate.parseOn(beforeContext);
  if (resultContext is Failure) return resultContext;
  final afterContext = after.parseOn(resultContext);
  if (afterContext is Failure) return afterContext;
  return afterContext.success(resultContext.value);
}
