I’m trying to make a

suspend

function execute its contents on a specific dispatcher. So far:``` suspend fun getFoo(): Foo? = coroutineScope { withContext(Dispatchers.IO) { retrieveFoo() } }``` Is this the best way to go about it?

I don't think there's a need to open a new

coroutineScope

, just doing

withContext

should work

Ah, perfect, thanks!

Also this is enough:

<http://Dispatchers.IO|Dispatchers.IO> { retrieve Foo }

There is invoke operator for Dispatcher

Oh, that's pretty fancy.

@gildor is you example equivalent to withContext? Does invoking the Dispatcher propagate the coroutineContext?

Yes, this is just a shortcut for withContext(SomeDispatcher)

I am trying it right now but can't find the

invoke

operator for

CoroutineDispatcher

in what version is this available? Or is it not part of the core?

Autocomplete works not so well with invoke operator, I should create an issue about this, but invoke is a part of the core https://kotlin.github.io/kotlinx.coroutines/kotlinx-coroutines-core/kotlinx.coroutines/invoke.html

I see, thank you
