Server

Deflate

letmut websocket = ratchet::accept_with(      socket,WebSocketConfig::default(),DeflateProvider,SubprotocolRegistry::default(),).await?;

Split

// A split operation will only fail if the WebSocket is already closed.let(mut sender,mut receiver) = websocket.split()?;loop{match receiver.read(&mut buf).await?{Message::Text =>{            sender.write(&mut buf,PayloadType::Text).await?;            buf.clear();}Message::Binary =>{            sender.write(&mut buf,PayloadType::Binary).await?;            buf.clear();}Message::Ping |Message::Pong =>{}Message::Close(_) =>breakOk(()),}}
