struct hash < std:: shared_ptr < T >> ;
(since C++11)

The template specialization of std::hash for std:: shared_ptr < T > allows users to obtain hashes of objects of type std:: shared_ptr < T > .

For a given std:: shared_ptr < T > p , this specialization ensures that std:: hash < std:: shared_ptr < T >> ( ) ( p ) == std:: hash < decltype ( p. get ( ) ) > ( ) ( p. get ( ) ) .
