Struct futures_channel::mpsc::UnboundedReceiver

pub struct UnboundedReceiver<T>(_);

The receiving end of an unbounded mpsc channel.

This value is created by the unbounded function.

Methods

impl<T> UnboundedReceiver<T>

pub fn close(&mut self)

Closes the receiving half of the channel, without dropping it.

This prevents any further messages from being sent on the channel while still enabling the receiver to drain messages that are buffered.

pub fn try_next(&mut self) -> Result<Option<T>, TryRecvError>

Tries to receive the next message without notifying a context if empty.

It is not recommended to call this function from inside of a future, only when you've otherwise arranged to be notified when the channel is no longer empty.

This function will panic if called after try_next or poll_next has returned None.

Trait Implementations

impl<T> Unpin for UnboundedReceiver<T>

impl<T: Debug> Debug for UnboundedReceiver<T>

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

Formats the value using the given formatter.

impl<T> Stream for UnboundedReceiver<T>

type Item = T

Values yielded by the stream.

fn poll_next(self: Pin<&mut Self>, cx: &mut Context) -> Poll<Option<T>>

Attempt to pull out the next value of this stream, registering the current task for wakeup if the value is not yet available, and returning None if the stream is exhausted.

fn size_hint(&self) -> (usize, Option<usize>)

Returns the bounds on the remaining length of the stream.

impl<T> FusedStream for UnboundedReceiver<T>

fn is_terminated(&self) -> bool

Returns true if the stream should no longer be polled.
