Cyberdeck

A library for easily creating WebRTC data channel connections in Rust.

cargo add cyberdeck

Signaling server

WebRTC works in it's most basic form by having the client and server exchange strings that represent their networking information. A signaling server is just some API that you exchange that information through. You can see a simple signaling server implemented with a single POST http handler here in this example here.

cargo run --example signaling_server
