Defined in header `<experimental/memory>` |  |
template<class T> struct hash< std::experimental::observer_ptr <T>>; |  | (library fundamentals TS v2)

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()).
