WebRTC 0.11 triggers a panic with "no process-level CryptoProvider available -- call CryptoProvider::install_default() before this point"
WebRTC 0.10 works fine -- but when I've upgraded to 0.11, there's a crash due to the changed with the rusttls backend.
We worked around this by installing our own crypto backend; but I didn't see anything in the Examples about this, so I figured I'd open an issue that can be closed as "works as intended" if this is part of the new API
(for those at home, something like)
rustls::crypto::ring::default_provider().install_default().unwrap()
Backtrace
Specifically, from a spawned task, the WebRTC negotiation code crashes with no process-level CryptoProvider available -- call CryptoProvider::install_default() before this point. This happens right after the rtc ice connection state changed to connected, so perhaps part of the changed DTLS codepath.
