Async wrapper API for browser provided WebRTC API.


Quickstart

use async_datachannel_wasm::{Message, PeerConnection, RtcConfig};
use futures::io::{AsyncReadExt, AsyncWriteExt, channel::mpsc};

let ice_servers = vec!["stun:stun.l.google.com:19302"];
let conf = RtcConfig::new(&ice_servers);
let (tx_sig_outbound, mut rx_sig_outbound) = mpsc::channel(32);
let (tx_sig_inbound, rx_sig_inbound) = mpsc::channel(32);
let listener = PeerConnection::new(ice_servers, (tx_sig_outbound, rx_sig_inbound))?;

// TODO: Wire up `tx_sig_inbound` and `rx_sig_outbound` to a signalling
// mechanism.

let mut dc = listener.dial("Hangout").await?;
dc.write(b"Hello").await?;

let mut buf = vec![0; 32];
let n = dc.read(&mut buf).await?;
assert_eq!(b"World", &buf[..n]);
