Do you have any idea of which library to use for async websockets? tokio-tungstenite seems like a good option although I have no experience with it.

Nothing in mind, haven't done a research yet. tokio-tungstenite looks good!

I think https://crates.io/crates/websocket looks like a reasonable contestant. But did not have time to test it extensively yet.

Would be awesome to be able to publish HTTP and WS on the same port: http://seanmonstar.com/post/175280388657/better-http-upgrades-with-hyper

Another reason to switch: websocket depends on hyper 0.10, which has security issues: https://rustsec.org/advisories/RUSTSEC-2020-0008.html

https://docs.rs/soketto/0.4.1/soketto/ looks like a very good candidate.
