Struct futures::channel::mpsc::UnboundedReceiver[][src]

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>
[src]

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.

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.
