Experimental dynamic select macro for crossbeam-channel

crossbeam-channel-select

An experimental dynamic_select! macro implemented as a procedural macro that supports selecting over iterators of Senders and Receivers;

Example:

use crossbeam_channel_select::dynamic_select;

fn main() {
    let (s0, r0) = crossbeam_channel::unbounded();

    let (s1, r1) = crossbeam_channel::unbounded();
    let (s2, r2) = crossbeam_channel::unbounded();
    let receivers = [r1, r2];

    s0.send("test").unwrap();
    s1.send("foo").unwrap();
    s2.send("bar").unwrap();

    for _ in 0..3 {
        dynamic_select! {
            recv(&r0) -> msg => {
                println!("Received {:?} from s0", msg);
            },
            recv_any(&receivers) -> msg, i => {
                println!("Received {:?} from receivers[{}]", msg, i);
            }
        }
    }
}
