Trait Implementations

impl<A, B, C, D> Future for EitherOf4Future<A, B, C, D>

where A: Future, B: Future, C: Future, D: Future,

type Output = EitherOf4<<A as Future>::Output, <B as Future>::Output, <C as Future>::Output, <D 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.
