Struct TryDrainFuture 

pub struct TryDrainFuture<'p, F: Future, M: SlotMemory<F>, D: FnMut(F::Output) -> Result<(), E>, E> { /* private fields */ }

The future returned from SlotPoller::try_drain.

This future will poll all the futures inside the slot poller. When one of them completes, the result is handled by the drain function, which can return an error if it wants to abort the drain.

Trait Implementations

impl<'p, F, M, D, E> Future for TryDrainFuture<'p, F, M, D, E>

where F: Future, M: SlotMemory<F>, D: FnMut(F::Output) -> Result<(), E>,

type Output = Result<(), 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.
