Cyberdeck

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

[dependencies]
cyberdeck = "0.0.12"

let mut cd = Cyberdeck::new(|e| async move {
    match e {
        CyberdeckEvent::DataChannelMessage(c, m) => {
            println!("Recieved a message from channel {}!", c.name());
            let msg_str = String::from_utf8(m.data.to_vec()).unwrap();
            println!("Message from DataChannel '{}': {}", c.name(), msg_str);
        }
        CyberdeckEvent::DataChannelStateChange(c) => {
            if c.state() == RTCDataChannelState::Open {
                println!("DataChannel '{}' opened", c.name());
                c.send_text("Connected to client!").await.unwrap();
            } else if c.state() == RTCDataChannelState::Closed {
                println!("DataChannel '{}' closed", c.name());
            }
        }
        CyberdeckEvent::PeerConnectionStateChange(s) => {
            println!("Peer connection state: {} ", s)
        }
    }
})
.await?;
let answer = cd.receive_offer(offer).await?;

You can try out this code by going to https://jsfiddle.net/ndgvLuyc/

1. Copy the code from "Browser base64 Session Description"
2. Open up a terminal and type in echo <code you copied from above> | cargo run --example receiver
3. Copy the response code in the terminal, and past it into "Rust base64 Session Description"
4. Hit connect and send messages

Limitations:

• Right now this only seems to work app to website. Not quite sure how to handle ICE servers yet. If you want to test this out though:

1. cargo run --example offer
2. copy the code
3. echo <code you copied from above> | cargo run --example receiver
4. copy the code the receiver app gives you
5. paste the code into the terminal of the offer app and press enter
