update_channel

A channel for single updatable values. The Updater can update a shared value and a Receiver can then update it's own internal value.

Example:

    use update_channel::channel_with;
    use std::thread::spawn;

    let (mut receiver, updater) = channel_with(0);
    assert_eq!(*receiver.borrow(), 0);

    spawn(move || {
        updater.update(2).unwrap(); // shared value is 2
        updater.update(12).unwrap(); // shared value is 12
    })
    .join().unwrap();

    // Shared value is 2 but internal value is 0
    assert_eq!(*receiver.borrow(), 0);
    // Update the latest value
    receiver.recv_update().unwrap();
    // Shared value is 12 and internal value 12
    assert_eq!(*receiver.borrow(), 12);
