This crate provides WebSocket support for Rocket via integration with Rocket's [connection upgrades] API.

Usage

  1. Depend on rocket_ws, renamed here to ws:

    [dependencies]
ws = { package = "rocket_ws", version ="=0.1.0-rc.3" }

  2. Use it!

    #[get("/echo")]
fn echo_stream(ws: ws::WebSocket) -> ws::Stream!['static] {
    ws::stream! { ws =>
        for await message in ws {
            yield message?;
        }
    }
}

See the crate docs for full details.
