Struct TraceFuture 

pub struct TraceFuture<'a, Fut: Future, C: CategoryString, S: AsTraceStrRef> { /* private fields */ }

Wraps a Future and writes duration events every time it’s polled. The duration events are connected by flow events.

Implementations

impl<'a, Fut: Future, C: CategoryString, S: AsTraceStrRef> TraceFuture<'a, Fut, C, S>

pub fn new(args: TraceFutureArgs<'a, C, S>, future: Fut) -> Self

Trait Implementations

impl<Fut: Future, C: CategoryString, S: AsTraceStrRef> Future for TraceFuture<'_, Fut, C, S>

type Output = <Fut as Future>::Output

The type of value produced on completion.

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

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