How do I wait for one or more blocked events?

I have a thread that reads from and sends to a TcpStream. I want to be able to send a message to the thread that will then write it to the stream.

I want this pseudocode:

pub fn spawn_thread(mut stream: TcpStream, commands: Receiver<String>) {
    std::thread::spawn(move || loop {
        // wait for either tcp data or command
        if /* got command */ {
            handle_write(/* ... */);
        } else if /* got tcp data */ {
            handle_read(/* ... */);
        }
    });
}

How would I go about doing this, or am I thinking about it wrong? I'm pretty new to Rust, coming from more of a C/C++ background. I'd think of using a select statement here. Is there any Rust equivalent?
