it still seems unclear whether to use callbackFlow vs channelFlow. It seems the latter respects operator fusion, but the prior does not?

[Dominaezzz]

One of them will throw an exception if you don't call awaitClose .

[Dominaezzz]

Only use callbackFlow if you're dealing with callbacks. Use channelFlow otherwise.

[zak.taccardi]

So they both respect operator fusion?

[Dominaezzz]

The only difference between them is the exception throwing.

[zak.taccardi]

I'm trying to think why I would ever want to use channelFlow because my only use case for it is to register/unregister callbacks

[Dominaezzz]

Some people want to do concurrent emit .

[zak.taccardi]

Ah, interesting

[ursus]

hmm why not just flow { .. } ? i thought that builder was main selling point of flow

[streetsofboston]

Because as soon as the provided lambda to the flow call ends/returns, the Flow that it returns ends/completes.

The callback/channelFlow builders provide a suspending awaitClose method allowing this lambda to suspend indefinitely.
