std::hash(std::shared_ptr)

From cppreference.com
< cpp‎ | memory‎ | shared ptr
 
 
 
 
 
template<class T> struct hash<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<T*>()(p.get()).
