Trait Implementations

impl<F1, F2> Future for Either<F1, F2>

where F1: Future, F2: Future<Output = F1::Output>,

type Output = <F1 as Future>::Output

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.
