      Description copied from class: Flowable
      Operator implementations (both source and intermediate) should implement this method that performs the necessary business logic and handles the incoming Subscribers.

      There is no need to call any of the plugin hooks on the current Flowable instance or the Subscriber; all hooks and basic safeguards have been applied by Flowable.subscribe(Subscriber) before this method gets called.

      Specified by:
      subscribeActual in class Flowable<R>
      Parameters:
      s - the incoming Subscriber, never null
