The std::iterator class template (used as a base class to provide typedefs) is deprecated in C++17. The C++ Standard has never required user-defined iterators to derive from std::iterator. A user-defined iterator should provide publicly accessible typedefs named iterator_category, value_type, difference_type, pointer, and reference. Note that value_type is required to be non-const, even for constant iterators.
