@gildor could you please explain why we need this extra code in each coroutine in the kotlin-coroutines-retrofit lib?

private fun Call<*>.registerOnCompletion(continuation: CancellableContinuation<*>) {
    continuation.invokeOnCompletion {
        if (continuation.isCancelled)
            try {
                cancel()       // why to cancel already cancelled coroutine?
            } catch (ex: Throwable) {
                //Ignore cancel exception
            }
    }
}

If coroutine is cancelled, then we should cancel retrofit request

yes, thanks. already realized this. initially i thought cancel is related to invokeOnCompletion lambda 😚
