Expose tokio::io::PollEvented please

[open-trade]

Widely used by the other crates, it is hard to upgrade these crates without PollEvented, Currently PollEvented is only crate visible, please make it outside visible.

PollEvented uses the mio crate in its public API, which we don't want to do anymore. Alternate apis are needed.

Did you give AsyncFd a look?

My use case has no underlying Unix file descriptor. I wanna wrap mio/src/sys/windows/named_pipe.rs

[carllerche]

I opened #3118 to track named pipes.

We cannot expose Mio as part of the public API as we may wish to alter the internals to avoid Mio (perhaps uring).

Alternate apis are needed.

It might have been nice to not make upgrading impossible until those newer apis were created.

Feel free to submit a PR adding named to pipe support. As an open source project, we have limited resources and make decisions based on what we are able to get done.

I don't need named pipe support.

It is a shame that unix is getting preferential treatment here with the AsyncFd trait. There will inevitably be developer requirements that will not be met by the built-in windows types. For instance the proposed named pipes PR doesn't have security descriptors, and given the breadth of windows APIs I doubt there will ever be a complete solution.
