I have a function that runs on main thread, which cannot be modified, like this:

fun calculate(): Int

And inside it I need to call a suspend function. How to do that? runBlocking?

[Robert Williams]

Depends whether completion of the suspend fun is required to determine the Int result

[Robert Williams]

If so, you'll need runBlocking

[Robert Williams]

Otherwise consider passing a Scope and launching another coroutine as a side-effect

Thanks 😉

That suspend function is the underlying calculation on another thread

[Robert Williams]

Well there's literally no reason to do it on another thread if you're going to block the main thread anyway
