This is Rust port of the WebUDP project, which is itself similar to the ideas presented in the article Simplifying WebRTC Connections (AKA Hacking the crap out of WebRTC)
Allows you to write a game server in rust with browser based clients and UDP-like networking. The server requires a tokio runtime and provides a non-blocking API for accepting WebRTC connections and sending and receiving WebRTC data channel messages from multiple clients.
This crate supports many of the necessary protocols in WebRTC to the barest minimum. You should expect ONLY WebRTC data channels to function, and only in unreliable, unordered mode.
