Implementation of the libp2p Transport trait for Websockets.
See the documentation of swarm and of libp2p in general to learn how to use the Transport
trait.
This library is used in a different way depending on whether you are compiling for emscripten or for a different operating system.
Emscripten
On emscripten, you can create a BrowserWsConfig object with BrowserWsConfig::new(). It can
then be used as a transport.
Listening on a websockets multiaddress isn't supported on emscripten. Dialing a multiaddress
which uses ws on top of TCP/IP will automatically use the XMLHttpRequest Javascript object.
use libp2p_websocket::BrowserWsConfig;
let ws_config = BrowserWsConfig::new();
// let _ = ws_config.dial("/ip4/40.41.42.43/tcp/12345/ws".parse().unwrap());
Other operating systems
On other operating systems, this library doesn't open any socket by itself. Instead it must be
plugged on top of another implementation of Transport such as TCP/IP.
This underlying transport must be put inside a WsConfig object through the
WsConfig::new() function.
