Struct futures::unsync::mpsc::UnboundedReceiver

pub struct UnboundedReceiver<T>(_);

The receiving end of an unbounded channel.

This is created by the unbounded function.

Methods

impl<T> UnboundedReceiver<T>

fn close(&mut self)

Closes the receiving half

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

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.
