How is the status of Transport maintained?

Hello, I am a developer of https://github.com/RingsNetwork/rings-node. (It‘s still in the bootstrap phase. It may be a little messy.)

We are trying to build a p2p network using WebRTC. We want to use the excellent rust-libp2p to help with our project development.

While reading the code in transports/webrtc, I found that the newly created RTCPeerConnection object does not declare on_peer_connection_state_change.

In our project, we use this event function to notify an external module of remote connection closing. Does rust-libp2p use other mechanisms to detect transport disconnection? What happens if a peer closes the connection to a WebRTC transport?

Our WebRTC supports is primarily in alpha state because it has not yet been battle-tested. It may very well be that we don't react closed connections correctly.

Personally, I am not very happy with how webrtc-rs is structured and I'd like to move to str0m: #3659

If you have WebRTC expertise, any help on that front would be much appreciated.
