Channel

Type Parameters:

E - element type

All Known Implementing Classes:

MpscChannel, SpscChannel
```
public interface Channel<E>
```
A minimal top level queue interface which allows producer/consumers access via separate interfaces. Channels may determine their capacity themselves with additional slack or resize themselves as powers of two etc. Consequently instead of having a definite concept of a "capacity" channels have a requested capacity and a maximum capacity. The requested capacity is the capacity requested when you create the channel and the maximum capacity is the size that the channel has resized itself up to.
