cancellable-timer

Crate that implements a timer with a sleep method that can be cancelled.

Example

```rust use std::time::Duration; use cancellable_timer::*;

fn main() { let (mut timer, canceller) = Timer::new2().unwrap();

// Spawn a thread that will cancel the timer after 2s.
std::thread::spawn(move || {
    std::thread::sleep(Duration::from_secs(2));
    println!("Stop the timer.");
    canceller.cancel();
});

println!("Wait 10s");
let r = timer.sleep(Duration::from_secs(10));
println!("Done: {:?}", r);

} ```
