public interface SubscriberBuilder<T,R> extends ProducesResult<R>
Subscriberand its result.
When built, this builder returns a
CompletionSubscriber, which encapsulates both a
Subscriber and a
CompletionStage that will be redeemed
with the result produced by the subscriber when the stream completes normally, or will be redeemed with an error
if the subscriber receives an error. A
SubscriberBuilder may represent a compound set of
stream stages and may complete exceptionally without receiving an error externally.
SubscriberBuilders may encapsulate error handling such as the
onErrorResume operator and recover from an externally received errors.
