I've got the handleCall(): Result = ... interface to implement, how would I invoke suspend functions in there? Via runBlocking?

Yup,

When bridging from the asynchronous (suspend) world to the synchronous world, runBlocking is your friend.

[kevin.cianfarini]

If the function is not marked as suspend, then your only option is to block. Be careful, though, because invoking runBlocking from another suspending function can result in deadlock

[reactormonk]

Makes sense, don't cross the streams.

Also if you call runBlocking from a thread that’s running some kind of message loop, and you call a suspend function that dispatches to that thread, it may deadlock (common in android).

[reactormonk]

So open a new Thread for the message loop? Is there a way I can tell coroutines to open a new thread for me, or should I use the Thread API?

[Zach Klippenstein (he/him) [MOD]]

Didn’t mean that. It’s just virtually impossible to use runBlocking in a way that is perfectly safe.
