Struct Receiver

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

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 wakeing 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.

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> Stream for Receiver<T>

type Item = T

Values yielded by the stream.

type Error = Never

Errors yielded by the stream.

fn poll_next( &mut self, cx: &mut Context<'_>, ) -> Poll<Option<Self::Item>, Self::Error>

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.
