Is there any way to retrieve the dispatcher from a coroutine context?

[Adam Powell]

yes, but there generally isn't a lot of reason to, why?

[eygraber]

I'm wrapping a 3rd party API that expects an executor in a suspendCancellableCoroutine. I want to be able to get the dispatcher from the continuation's context and turn that into an executor

[Adam Powell]

thought that might be it. 🙂 You don't need to. Use a directExecutor and just resume the continuation with the right result, it'll dispatch to the right CoroutineDispatcher as part of resuming the continuation

[eygraber]

Is that from Guava?

[Adam Powell]

Yes but you can make your own trivially:

object DirectExecutor : Executor {
  override fun execute(r: Runnable) {
    r.run()
  }
}

Interesting. Thanks!
