The receiving end of a bounded mpsc channel.

This value is created by the channel function.

Methods

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.

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