RxDiffUtil is an Rx wrapper around the Android DiffUtil library for the
RecyclerView widget. It handles threading and reacts to concurrent changes
to the adapter with a ConcurrentModificationException.
All computation is done on the thread defined by the upstream Flowable,
while the application of the diff result and all terminal events are
propagated on the Android main thread.
The resulting Completable expects upstream to honor backpressure and shares
the subscription to reduce concurrent changes to the adapter.
Convert any Flowable to a Completable applying all changes as diff to the
provided adapter.
