Is there something similar to `yield` that does not dispatch if `isDispatchNeeded == false`?

Is there something similar to yield that does not dispatch if isDispatchNeeded == false?

[Patrick Steiger]

Context is I’m starting a coroutine with CoroutineStart.UNDISPATCHED but at some point I want to check for cancellation and run the code in the correct coroutine context present in scope, but I want to avoid dispatch if dispatcher is immediate and it was already called in the right thread

If you are only interested in cancellation, you may use ensureActive instead https://kotlinlang.org/api/kotlinx.coroutines/kotlinx-coroutines-core/kotlinx.coroutines/ensure-active.html

@bezrukov no, because it’s started undispatched (random caller thread) and ensureActive would not dispatch it if needed
