The template specialization of std::hash for std:: experimental :: observer_ptr < T > allows users to obtain hashes of objects of type std:: experimental :: observer_ptr < T > .
For a given std:: experimental :: observer_ptr < T > p , this specialization ensures that std:: hash < std:: experimental :: observer_ptr < T >> ( ) ( p ) == std:: hash < T * > ( ) ( p. get ( ) ) .
