Currently I have a

suspend fun <http://CoroutineContext.xyz|CoroutineContext.xyz>()

and I perform a check and then call

coroutineContext.cancel()

and then throw a

CancellationException

What do you mean by check? Also note that whenever you switch contexts (withContext), the runnables will automatically not be called if the coroutine is cancelled

If you also just want to insert breakpoints during an execution, you can use

yield()

So you suggest to just throw the exception?

Throwing alone should work

You also might not want to use both

suspend

and

CoroutineScope

extensions in one method. Suspending functions are long executions whereas coroutine scope functions launch and return quickly

It was only to cancel the job

Thanks!
