Native WebSocket support

[net]

I think Rocket would benefit heavily from native WebSocket support. Even better would be something similar to Phoenix's channels.

It's great to see such a comprehensive web framework for Rust coming together!

@net did you manage to combine rocket with eg. websocket on the same host:port?
I'm trying to upgrade connection to ws, but no luck so far :(

This is indeed planned.

@SergioBenitez got any suggestions for how one could manually add web socket support?

@wagenet Do you mean to Rocket or to your web application? The former is subtle is it requires a lot of design work, but the latter should be straightforward. You should be able to use the websocket or ws-rs crates as they are intended. You won't be able to use the same port for both servers, of course. And, you'll need to spawn one of the two servers in a separate thread so that one server doesn't block the other one from starting. Should you choose to do this, your main function would look something like:

fn main() {
    thread::spawn(|| {
        listen("127.0.0.1:3012", |out| {
            move |msg| {
                out.send(msg)
           }
        })
    })

    rocket.ignite()..more()..launch()
}

@SergioBenitez thanks :) I ended up discovering this sort of approach myself.
