With a `suspend () -> Unit`, you can create a `...

With a suspend () -> Unit, you can create a Continuation by calling createCoroutine(). How can you create a CancelableContinuation?

[simon.vergauwen]

You cannot afaik. It's private to KoltinX Coroutines.

It's marked with @InternalCoroutinesApi

[hfhbd]

Yeah, but this starts the coroutine, I would like to create and start it later

[simon.vergauwen]

That is also all internal machinery, but hidden away more than this. You can follow these implementations to see where they lead, but it leads to more internal and @InternalCoroutinesApi based code.

[simon.vergauwen]

What is your use-case for doing this?

[ephemient]

launch(start = CoroutineStart.LAZY) { ... } will not run the code until the resulting Job is `.start()`ed

[hfhbd]

I read https://github.com/JetBrains/kotlin/blob/master/compiler/backend/src/org/jetbrains/kotlin/codegen/coroutines/coroutines-codegen.md and tried to play with it.

Maybe you’re looking for suspendCancellableCoroutine ?
