NAME¶

std::hash(std::shared_ptr) - std::hash(std::shared_ptr)

Synopsis¶

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