Struct Timed 

pub struct Timed<F>
where
    F: Future,
{ /* private fields */ }

Instrumentation to record the timing of a wrapped future.

The Timed wraps any future and records the inner future’s busy and idle time. The timing is returned together with the inner future’s output once it resolves ready.

Examples

To wrap a future, use the timed function.

    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());

Trait Implementations

impl<F> Future for Timed<F>

where F: Future,

type Output = TimingOutput<<F as Future>::Output>

The type of value produced on completion.

fn poll( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<TimingOutput<F::Output>>

Attempts to resolve the future to a final value, registering the current task for wakeup if the value is not yet available.

impl<'__pin, F> Unpin for Timed<F>

where PinnedFieldsOf<__Origin<'__pin, F>>: Unpin, F: Future,
