WASI support

[mankinskin]

In an effort to make tokio compatible with wasm32-wasi (tokio-rs/tokio#1597), it might make sense to make this crate WASI compatible aswell.

I have an old tree: https://github.com/Thomasdezeeuw/mio/tree/wasm32-wasi, but its not functional and I don't have time to work on this.

@mankinskin #1395.

@Thomasdezeeuw I have no experience in this codebase whatsoever so unfortunately I can't really help with this on the spot..

Closing this due to lack of interest.

Can you clarify what you mean by lack of interest? As far as I can tell, this issue is blocked by missing WASI API (implementation: WebAssembly/WASI#312)

Mio can't implement socket connections until it is supported by the platform. I don't know of anything else that Mio can implement which is supported by WASI today

It's true that Mio couldn't support socket creation, but as far as I can tell it is possible to pass a socket "from the outside" to wasm and use it from there. For example sock_recv has been part of the WASI API for a while. Mio can also already (sort of) implement Poll using poll_oneof. So an experimental implementation of parts of Mio is possible.

Re: lack of interest. This issue has seen very little activity and I know of no development effort to port Mio (except of my own, linked previously).

Is this permanently closed?

[Thomasdezeeuw]

@xpepermint no this issue just hasn't seen any real activity so that's why I closed it. We're still open to supporting WASM/WASI.
