I recently revisited a crate I worked on a while ago to make it easier to use TLS with a hyper server: GitHub - tmccombs/tls-listener: Rust wrapper around a connection listener to support TLS..
I rewrote it to be compatible with tokio 1.0 and hyper 0.14 (and switched to using rustls).
I'd love some feedback on it.
It looks reasonable to me. We do sometimes have questions on how to do this on the Tokio discord, so I'll keep a link around.
One feature you might want would be a timeout on the futures in that FuturesUnordered so I can't just open a connection and do nothing to DoS the server.
Additionally the github page could use a link to the crate's entries on crates.io and docs.rs.
