I assume this to not be worth handling since I expect this package to now be obsolete (see bug#1110778),
Matthias Geiger noticed that librust-async-tungstenite-dev depends on it, so while we may well still decide to get rid of rust-async-tls in the medium term, it's not something that's likely to happen imminently.
but if for some reason this package is kept, then please do tell and if you need help patching to work with the newer rustls-native-certs crate.
I don't forsee any problems here. All that should be needed is to drop the "rustls-native-certs-0.6.patch" and regenerate the packaging (or manually tweak the (build-)deps). FwIW I've been going through the reverse dependencies of rustls-native-certs and unless I've missed something, all of them now seem to have a "patch or other trivial fix" available. I was going to propose starting the update after the rust-rustls-webpki update and the recent changes to the tungstenite crates ( tungstenite/async-tungstenite/ tokio-tungstenite ) migrated to testing.
