A Publisher can serve multiple subscribers subscribed dynamically at various points in time. In the case of multiple subscribers the Publisher should respect the processing rates of all of its subscribers (possibly allowing for a bounded drift between them). It must eventually clean up its resources after all of its subscribers have been unsubscribed and shut down. A Publisher will typically support fanning out to multiple Subscribers in order to support the dynamic assembly of processing networks from building blocks that can freely be shared. -A *Subscriber* is a component that accepts a sequenced stream of elements provided by a Publisher. At any given time a Subscriber might be subscribed to at most one Publisher. It provides the callback onNext to be called by the upstream Producer, accepting an element that is to be asynchronously processed or enqueued without blocking the Producer. +A *Subscriber* is a component that accepts a sequenced stream of elements provided by a Publisher. At any given time a Subscriber might be subscribed to at most one Publisher. It provides the callback onNext to be called by the upstream Producer, accepting an element that is to be asynchronously processed or enqueued without blocking the Publisher. A Subscriber communicates demand to the Publisher via a *Subscription* which is passed to the Subscriber after the subscription has been established. The Subscription exposes the requestMore(int) method that is used by the Subscriber to signal demand to the Publisher. For each of its subscribers the Publisher obeys the following invariant:
