Windows UDS Support

[mattsre]

Version

Tokio version - 0.2.11

Platform

Windows 10 Pro - 1909 (November Update)

Description

I'd like to be able to use UDS on Windows with Tokio. Windows 10 introduced support for unix sockets in late 2017 to Insiders builds, and the spring 2018 general Windows 10 release. Building this functionality into Tokio allows downstream ecosystems, such as Tonic's, to use this support to enhance their own offerings and examples.

Looks like the folks at Azure took a run at this, but it's likely an out of date solution now:

This seems like it should be added to mio first.

Because we hid PollEvented, this is going to need some additional support. I don't know much about UDS on windows. Will it work w/ AFD (see how tcp/udp are now implemented on windows)? or does it need to go via IOCP?

Just curious if there was any update on when/if this could happen. Seems to be blocking denoland/deno#10750 over in Deno land, which I'm eagerly watching...

I'm interested in this as well. I'll muck about with this and see what I can come up with. This would have to start with mio, as has already been mentioned.

We don't currently have any plans to work on this feature, but if someone wants to figure out how it works and implement it, I would be happy to review such a PR.

afaik, it will require changes in mio, which in turns needs std support. This might take a while. see rust-lang/rust#56533
