Struct tokio_stream::stream_ext::try_next::TryNext

pub struct TryNext<'a, St: ?Sized> {
    inner: Next<'a, St>,
    _pin: PhantomPinned,
}

Future for the try_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

inner: Next<'a, St>

_pin: PhantomPinned

Implementations

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

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

Trait Implementations

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

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

Formats the value using the given formatter.

impl<T, E, St: ?Sized + Stream<Item = Result<T, E>> + Unpin> Future for TryNext<'_, St>

type Output = Result<Option<T>, E>

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.
