Helpers for IoBackend.

Provided Methods

fn with_backend<F>( &self, future: F ) -> (WithBackend<'_, Self::Backend, F>, Option<PollingHandle<'_>>)

where F: Future,

Builds a composite future that also polls the backend future.

If second tuple element is not None, then the caller is responsible for registering and handling read-readiness events.

fn block_on<F>(&self, fut: F) -> <F as Future>::Output

where F: Future,

Executes a future to completion.

This function uses mfio’s mini-executor that is able to resolve an arbitrary future that is either awoken externally, or through exported handle’s readiness events.

Object Safety

This trait is not object safe.
