Type Definition mhost::app::modules::PartialResult[−][src]

type PartialResult<T> = Result<T, PartialError>;

Return type for App modules that go through multiple steps

  • An App module might go through multiple distinct steps to eventually fulfill its task. Along this
  • way, errors might occur. Errors should be reported using Result. But what if a step finishes
  • without errors but still couldn’t obtain the necessary information for the next step to proceed?
  • For this use case, PartialResult works similar to an Either type for the Result::Err side of the
  • execution.
  • Think of it as a means for early returns.
