Hi guys, this is a question of concept. Under which circumstances would it be beneficial to

launch

a single coroutine in a

runBlocking

scope? Example

fun foo() {
	runBlocking {
		launch {
			// some suspend functions
		}
	}
}

Instead of

fun foo() {
	runBlocking {
		// some suspend functions
	}
}

Just one launch, not much benefit. But if you do multiple launch-es, you can do stuff in parallel and have runBlocking return when they are all done.

That's what I thought. Is there any benefit for a single

launch

though?

There is no benefit at all for a single

launch

.

No benefit. A single

launch

inside

runBlocking

should be totally transparent.

The man himself hath spoken

To be sure; a

runBlocking

with j*ust* a single

launch

is totally transparent, but it could still have one

launch

and some other code, which then would happen in parallel. 🙂

runBlocking {
    launch { .... }
    here() 
    is()
    someOtherCode()
}
