hash<std::shared_ptr>
Deduction guides (C++17)
template< class T >
struct hash<std::shared_ptr <T>>;
(since C++11)
struct hash<std::shared_ptr <T>>;
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()).
