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:

1. Bounded channel with limited capacity.

2. Unbounded channel with unlimited capacity.

A channel has the `Sender` and `Receiver` side. Both sides are cloneable and can be shared

among multiple threads.

When all `Sender`s or all `Receiver`s 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 `Sender::close()` or

`Receiver::close()`.

## Examples

```rust

let (s, r) = async_channel::unbounded();

assert_eq!(s.send("Hello").await, Ok(()));

assert_eq!(r.recv().await, Ok("Hello"));

```
