Hi! What will happen if I call multiple suspend functions from launch like so:

myScope.launch {
  suspendingFunction1()
  someFlow
    .onEach { suspendingFunction2() }
    .collect { 
      someChannel.send(Unit) // 'send' is also a suspending fun
    }
}

Will each of them block? (inside this coroutine)

none of them block, but they will each suspend. I'm not sure what you would expect other wise?

If they all suspend, then the execution will look like:
1. suspendingFunction1() suspends
2. suspendingFunction1() resumes
3. someFlow.onEach (returns a Flow)
4. collect suspends
5. someFlow emits
6. suspendingFunction2() suspends
7. suspendingFunction2() resumes
8. someChannel.send suspends
9. someChannel.send resumes
10. Repeat 5-9 until someFlow completes
11. collect resumes

I forgot to mention this might be a silly question, I'm starting to learn this and my understanding hasn't yet formed a good mental model of how everything behaves...

zachklipp This is awesome, thank you very much, just what I've needed. I think I might think of each suspend function in terms of continuation (which I now recall it actually is). Whenever I see a call to suspend function I may translate everything after a call to it as a continuation to be called when body of said function will complete executing on current Dispatcher.

That’s exactly what I do! Turn everything back into callbacks in my head.
