Struct Next 

pub struct Next<'a, St: ?Sized> {
    stream: &'a mut St,
    _pin: PhantomPinned,
}

Future for the next method.

Cancel safety

This method is cancel safe. It only holds onto a reference to the underlying stream, so dropping it will never lose a value.

Fields

stream: &'a mut St

_pin: PhantomPinned

Implementations

impl<'a, St: ?Sized> Next<'a, St>

pub(super) fn new(stream: &'a mut St) -> Self

Trait Implementations

impl<'a, St: Debug + ?Sized> Debug for Next<'a, St>

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

Formats the value using the given formatter.

impl<St: ?Sized + Stream + Unpin> Future for Next<'_, St>

type Output = Option<<St as Stream>::Item>

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.

impl<'__pin, 'a, St: ?Sized> Unpin for Next<'a, St>
