Hi.
Is there any zero-capacity channels that always can send without suspension?
It seems Channel(0)#send will suspend unless any receivers are consuming values.
It is okay if values will be lost when no receivers are consuming.

So you want a rendezvous channel that only facilitates a rendezvous initiated by the receiver (instead of the sender)?

Sounds like a conflated broadcast channel

Conflate!

Or just use offer.

You should use offer. then depending on channel capacity:
CONFLATED -> offer always returns true, receiver is guaranteed to get the most recent value.
RENDEZVOUS -> offer returns false when receiver is not waiting, the value is lost.

Thanks everyone, RENDEZVOUS Channel’s offer is exactly the one I was looking for!
I was considered using conflated channels, but that channel has at most one buffer so receivers will be received value when start consuming.
