#[must_use = "futures do nothing unless polled"]
pub struct NextIfEq<'a, St: Stream, T: ?Sized> { /* fields omitted */ }

Future for the Peekable::next_if_eq method.

Trait Implementations

impl<St, T> Debug for NextIfEq<'_, St, T> where
    St: Stream + Debug,
    St::Item: Debug,
    T: ?Sized, 

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

Formats the value using the given formatter.

impl<St, T> FusedFuture for NextIfEq<'_, St, T> where
    St: Stream,
    T: ?Sized,
    St::Item: PartialEq<T>, 

fn is_terminated(&self) -> bool

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

impl<St, T> Future for NextIfEq<'_, St, T> where
    St: Stream,
    T: ?Sized,
    St::Item: PartialEq<T>, 

type Output = Option<St::Item>

The type of value produced on completion.

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

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

impl<'__pin, 'a, St: Stream, T: ?Sized> Unpin for NextIfEq<'a, St, T> where
    __Origin<'__pin, 'a, St, T>: Unpin,
