Should the client disconnect right away?

[fra-luc]

Hi and thanks for your work!
I'm trying to connect to a socketio server written with socketioxide.
The client code is very simple:

fn main() {
    use rust_socketio::{ClientBuilder, Payload, RawClient};

    let callback = |payload: Payload, _socket: RawClient| {
        match payload {
            Payload::Text(values) => println!("Received: {:#?}", values),
            Payload::Binary(bin_data) => println!("Received bytes: {:#?}", bin_data),
            _ => println!("Received: {:#?}", payload),
        }
    };

    let socket = ClientBuilder::new("http://localhost:3000/")
        .namespace("/")
        .on("messages", callback)
        .on("error", |err, _| eprintln!("Error: {:#?}", err))
        .connect()
        .expect("Connection failed");


    println!("Emitting to create_room");

    socket
        .emit("create_room", "")
        .expect("Server unreachable");
}

I can see on the server side that the client is connected.
The problem is that this client exits right away!
And the message emitted on event create_room doesn't seem to reach the server.
Is this the expected behaviour?

I have an equivalent client written in Python and it works fine...

Thank you!
