I want to create my own ContinuationInterceptor, but also use an existing CoroutineDispatcher to have all coroutines run on a specific thread. At first I thought I'd just extend CoroutineDispatcher , delegate everything and override interceptContinuation , but the interceptor methods are both final there. What's the recommended way of doing this, can I just combine the dispatcher and my interceptor?

You can create a single-threaded ExecutorService and then call asCoroutineDispatcher on it:

thats what I'm already doing. I also want some custom CoroutineInterceptor logic, that I'd like to "combine" with the dispatcher

Could you do something like this:

class MyDispatcher(private val dispatcher: CoroutineDispatcher) : ContinuationInterceptor by dispatcher {
    override fun interceptContinuation(....) ....
}
