Struct Receiver 

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

Reusable receiver of a multi-shot channel.

A Receiver can be used to receive a value using the Future returned by recv. It can also produce a one-shot Sender with the sender method, provided that there is currently no live sender.

A receiver can be created with the channel function or with the new method.

Implementations

impl<T> Receiver<T>

pub fn new() -> Self

Creates a new receiver.

pub fn sender(&mut self) -> Option<Sender<T>>

Returns a new sender if there is currently no live sender.

This operation is wait-free. It is guaranteed to succeed (i) on its first invocation and (ii) on further invocations if the future returned by recv has been awaited (i.e. polled to completion) after the previous sender was created.

pub fn recv(&mut self) -> Recv<'_, T>

Receives a message asynchronously.

If the channel is empty, the future returned by this method waits until there is a message. If there is no live sender and no message, the future completes and returns an error.
