AsyncOnSubscribe

object AsyncOnSubscribe

EXPERIMENTAL A utility class to create Observables that start acting when subscribed to and responds correctly to back pressure requests from Subscribers.

Semantics:

  • generator is called to provide an initial state on each new subscription
  • next is called with the last state and a requested amount of items to provide a new state and an Observable that (potentially asynchronously) emits up to requested items.
  • onUnsubscribe is called with the state provided by the last next call when the Subscriber unsubscribes
