mapBusiness<R> method

Result<R> mapBusiness<R>(Failure ifBusinessError, Result<R> onData(T data))

Transport-aware mapping: maps the success value while letting TransportFailures and CancelledFailures pass through UNCHANGED; substitutes ifBusinessError for any other failure so feature-specific copy is preserved for real server errors. (An offline or cancelled request is not a business error and must not be relabelled as one.)

return result.mapBusiness(
  const ProfileFailure(),
  (data) => Ok(data.toDomain()),
);

Implementation

Result<R> mapBusiness<R>(
  Failure ifBusinessError,
  Result<R> Function(T data) onData,
) =>
    switch (this) {
      Ok(:final value) => onData(value),
      Err(:final failure) =>
        failure is TransportFailure || failure is CancelledFailure
            ? Err(failure)
            : Err(ifBusinessError),
    };
