Struct InstrumentFuture

pub struct InstrumentFuture<F, I, H> { /* private fields */ }

Attaches a I-typed instruments to the result of an F-typed Future.

Implementations

impl<F, I, H> InstrumentFuture<F, I, H>

pub fn new(instrument: I, handle: H, future: F) -> Self

Wraps a future, instrumenting its value if successful.

Trait Implementations

impl<F: Debug, I: Debug, H: Debug> Debug for InstrumentFuture<F, I, H>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<F, I, H, T, E> Future for InstrumentFuture<F, I, H>

where F: Future<Output = Result<T, E>>, I: Instrument<H, T>,

type Output = Result<<I as Instrument<H, T>>::Output, E>

The type of value produced on completion.

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

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