source§

impl<F> TraceFuture for F
where F: Future,

source§

fn trace_task<I: Instrument>( self, instrument: &mut I ) -> TraceTaskFuture<'_, Self, I> ⓘ

Trace a Future’s task execution. The underlying Instrument calls on_enter when the future is first polled, and calls on_exit when it completes (returns Poll::Ready). This is useful for analyzing the total time it takes for your future to complete (note that this is different from the real CPU time the task consumes).
source§

fn trace_poll<I: Instrument>( self, instrument: &mut I ) -> TracePollFuture<'_, Self, I> ⓘ

Trace a Future poll execution. The underlying Instrument calls on_enter every time prior to the underlying future being polled, and calls and calls on_exit when it completes (returns on_exit right after the poll call completes, regardless of whether the underlying future completed or not. This is useful for analyzing the time it takes to poll your future (ie, actual CPU time used).
source§

fn trace_task_and_poll<'a, I1: Instrument, I2: Instrument>( self, task_instrument: &'a mut I1, poll_instrument: &'a mut I2 ) -> TraceTaskAndPollFuture<'a, Self, I1, I2> ⓘ

The first underlying Instrument (task_instrument) acts exactly as trace_task, and the second underlying Instrument (poll_instrument) acts exactly as trace_poll.
source§

impl<T, U> TryFrom<U> for T
where U: Into<T>,

§

type Error = Infallible

The type returned in the event of a conversion error.
source§

Performs the conversion.
source§

impl<T, U> TryInto<U> for T
where U: TryFrom<T>,

§

type Error = <U as TryFrom<T>>::Error

The type returned in the event of a conversion error.
source§

fn try_into(self) -> Result<U, <U as TryFrom<T>>::Error>
