flatMap<R> method

Result<R> flatMap<R>(Result<R> transform(T value))

Chains sequential asynchronous or synchronous monadic operations where the transform callback yields another encapsulated Result envelope.

Prevents flat nested structures like Result<Result<R>> by keeping execution pipelines linear.

Implementation

Result<R> flatMap<R>(Result<R> Function(T value) transform) => switch (this) {
      _SuccessResult<T>(success: final success) => transform(success.value),
      _FailureResult<T>(failure: final failure) => Result<R>.failure(failure),
    };
