Function timed 

pub fn timed<Fut, F>(fut: Fut, f: F) -> Timed<Fut, F> 
where
    Fut: Future,
    F: FnOnce(Timing),

Instrument a future to record its timing.

The busy and idle time for the future will be passed as an argument to the provided closure. See the documentation for Timing for more details. In general, it is more straightforward to use the TimedFutureExt extension trait to attach instrument a future directly.

Examples

use future_timed::{timed, Timing};
    let output = timed(some_async_fn(), |Timing { idle, busy }| {
        assert!(!idle.is_zero());
        assert!(!busy.is_zero());
    })
    .await;

    do_something_with_output(output);
