std::hash

 

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()).	(until C++17)
std::hash<std::shared_ptr<T>>()(p) == std::hash<typename std::shared_ptr<T>::element_type*>()(p.get()).	(since C++17)
