Trait Implementations

impl<F> Debug for Flatten<F> where
    Flatten<F, <F as Future>::Output>: Debug,
    F: Future, 

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

Formats the value using the given formatter.

impl<F> FusedFuture for Flatten<F> where
    Flatten<F, <F as Future>::Output>: FusedFuture,
    F: Future, 

fn is_terminated(&self) -> bool

Returns true if the underlying future should no longer be polled.

impl<F> Future for Flatten<F> where
    Flatten<F, <F as Future>::Output>: Future,
    F: Future, 

type Output = <Flatten<F, <F as Future>::Output> as Future>::Output

The type of value produced on completion.

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