Is there something similar to

yield

that does not dispatch if

isDispatchNeeded == false

?

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
