FutureObserver

public final class FutureObserver<Value> : AnyFutureObserver

extension FutureObserver: Equatable

Used to keep track of observers, in order to supply the ability to remove observers from a future, if the result of a future is no longer interesting.

The following methods return a FutureObserver:

Future<Value>.whenResolved()
Future<Value>.whenFulfilled()
Future<Value>.whenRejected()

remove()
Removes the observer from its associated future. The observer will not be invoked after a call to remove() is made.
