Package: rust-rustls I hope to update tokio in Debian to the latest version soon, tokio itself is not semver-breaking, but one of it's closely coupled dependencies mio is. The new versions of tokio, tokio-macros, mio and signal-hook-mio are now available in experimental.
The main rustls crate does not appear to use mio, but the rustls-examples subcrate does. I was able to build the package successfully after bumping the debian and cargo dependencies on mio.
