§Subscriber
A Subscriber is an [Observer] that is also a [SubscriptionLike], so it can clean itself up upon unsubscribe.
§For Implementations
A struct implementing Subscriber should have all their fields as private, as users will never directly interact with a Subscriber.
§Inlining
A subscribers [Observer] functions like next, error and complete
that just simply forward the signal to its destination should always
be #[inline].
