is there a way to schedule a block of code to run on a block completion when run with

withContext

? (I’m trying to time some functions)

along the same lines, would using

invokeOnCompletion

with async be a “good” idea

Not sure exactly what the use case is but maybe try

runBlocking

?

What does "to run on a block completion" mean?

suspend fun someFun() = withContext(<http://Dispatcher.IO|Dispatcher.IO>) {
 …
}

or

coroutineScope

, please, use it, if you are able to call it from coroutine/suspend fun, as

runBlocking

is blocking, and

coroutineScope

is suspending

@Dominaezzz,

withContext

takes a parameter `block`; that block’s completion; think of it like

try {
   block()
} finally {
   method()
}

Oh, "block" -> "block's". Got it.

You can put

withContext

in try/finally, no?

hmm, withContextTimed with the same arguments, cool

will try that
