Is there a library to provide extension functions for RxJava 1 types? Like

Single.await()

? The official lib only supports RxJava 2 😞

No support has been droped

do you mind explaining more about implementing one?

You can use

suspendCoroutine

Here's an example:

suspend fun <T> Single<T>.await(): T = supendCancellableCoroutine { cont ->
	val disposable = subscribe(
		{ cont.resume(it) }, // onSuccess
		{ cont.resumeWithException(it) } // onError
	)
	
	cont.invokeOnCancellation {
		disposable.dispose()
	}
}

thank you very much! appreciate it 🙂

Actually my exmple would work with RxJava 2 (I just tried)

The Rx2 adapter library actually does a lot of work to manage backpressure etc, you might want to consider just using that library with the Rx1/Rx2 adapter library from David Karnok

You can copy old (dropped) implementation of Rx1 adapter to you project
