Hey @christian3042, you asked a feedback in #479.

• First you need to have either tracing_subscriber or more simply env_logger if you want to print the log you are emitting.
• For code clarity i recommend to define event handlers as functions rather than closures:

fn on_connect(socket: SocketRef) {
    socket.on("send-message", on_send_message);
}
async fn on_send_message(socket: SocketRef, Data(request): Data<ChatRequest>) {
    info!("Join chat");
    socket.join("chat");

    let response = ChatResponse {
        message: request.message,
    };
    socket
        .within("chat")
        .emit("message-res", &response)
        .await
        .unwrap();
}

Thanks for your feedback! Using the tracing mechanism already helped a lot to find some issues.
I will replace the closures in my app soon for better readability. Since I'm new to Rust and socketioxide I still have to learn a few things.
