@ExperimentalCoroutinesApi fun <T : Any> rxFlowable(
    context: CoroutineContext = EmptyCoroutineContext,
    block: suspend ProducerScope<T>.() -> Unit
): Flowable<T>

Creates cold flowable that will run a given block in a coroutine. Every time the returned flowable is subscribed, it starts a new coroutine. Coroutine emits items with send. Unsubscribing cancels running coroutine.

Invocations of send are suspended appropriately when subscribers apply back-pressure and to ensure that onNext is not invoked concurrently.

Coroutine action Signal to subscriber
send onNext
Normal completion or close without cause onComplete
Failure with exception or close with cause onError

Coroutine context can be specified with context argument. If the context does not have any dispatcher nor any other ContinuationInterceptor, then Dispatchers.Default is used. Method throws IllegalArgumentException if provided context contains a Job instance.
