An async multi-producer multi-consumer channel, where each message can be received by only
one of all existing consumers.
There are two kinds of channels:
- Bounded channel with limited capacity.
- Unbounded channel with unlimited capacity.
A channel has the
Receiver side. Both sides are cloneable and can be shared
among multiple threads.
Senders or all
Receivers are dropped, the channel becomes closed. When a
channel is closed, no more messages can be sent, but remaining messages can still be received.
The channel can also be closed manually by calling
let (s, r) = async_channel::unbounded();
