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!

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.
