Function timed 

pub fn timed<F>(fut: F) -> Timed<F> 
where
    F: Future,

Instrument a future to record its timing

The busy and idle time for the future will be recorded separately in the result together with the output of the wrapped future. See the documentation for Timing for more details.

Examples

    let output = future_timing::timed(some_async_fn()).await;
    let (timing, future_output) = output.into_parts();

    do_something_with_output(future_output);

    assert!(!timing.idle().is_zero());
    assert!(!timing.busy().is_zero());
