Synopsis


constexpr const_reverse_iterator rbegin() const noexcept; (since C++17)
constexpr const_reverse_iterator crbegin() const noexcept; (since C++17)

      std::string_view str_view("abcdef");


      std::copy(str_view.rbegin(), std::next(str_view.rbegin(), 3), out_it);
      *out_it = '\n';


      std::copy(str_view.crbegin(), std::next(str_view.crbegin(), 3), out_it);
      *out_it = '\n';
  }
