Is there a tidy way to wait for any of`n` coroutines to finish (don’t care which one finishes first, just give me the first one)

You want a race of coroutines with only one winner, and losers cancelled?

No, the others keep going — I just want to respond as soon as the first one finishes and possibly add another coroutine to do yet more work

@mp You can hack into an

actor

I think. You can launch 4 (or

k

) coroutines inside it that then call

receive()

in a

while(isActive)

loop before doing work with the received value.

interesting, I’ll look into it

It might be worth checking out the source for

AwaitAll

which does a similar thing: https://github.com/Kotlin/kotlinx.coroutines/blob/master/common/kotlinx-coroutines-core-common/src/Await.kt#L59
