HI folks, what is the difference of

Channel.offer

and

Channel.send

, I know that send suspend and offer don't, but what is the usage difference?

With

send

, the receiver(s) will always get the sent value. With

offer

, the receiver(s) may not get offered value, it could be dropped if the buffer is full.

you can use offer from non-suspend function, which is very useful when you write adapters for coroutines from non-coroutine code. Also send is a way to achieve backpressure, slowdown senders if consumer is slower
