Struct futures_channel::mpsc::Receiver

pub struct Receiver<T> { /* fields omitted */ }

The receiving end of a bounded mpsc channel.

This value is created by the channel function.

Implementations

impl<T> Receiver<T>

pub fn close(&mut self)

Closes the receiving half of a 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: Debug> Debug for Receiver<T>

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

Formats the value using the given formatter.

impl<T> Drop for Receiver<T>

fn drop(&mut self)

Executes the destructor for this type.

impl<T> FusedStream for Receiver<T>

fn is_terminated(&self) -> bool

Returns true if the stream should no longer be polled.

impl<T> Stream for Receiver<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.

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

Returns the bounds on the remaining length of the stream.
