Detailed Description

Observer to monitor the lifetime of a shared resource.

A shared resource whose lifetime isn't managed via a smart pointer can become a dangling reference. When a resource is centrally managed, e.g. via a singleton, the singleton interface can be adapted to keep track of the shared resources lifetime via an "observer" object that shares the same lifetime.

This class wraps a type-erased non-owning observer that cannot be promoted to a shared handle.
