💅 NAME 💅

std::extents::dynamic-index-inv — std::extents::dynamic-index-inv

Okay bestie, this page is std::extent...ic-index-inv(3) from the C++ Standard Libary manual — yes, that’s the exact spelling on the page, we’re keeping it 💖. It’s all about std::extents::dynamic-index-inv, and it’s giving very private-helper energy.

🌸 Synopsis 🌸

          private:

              template< class OtherIndexType >
       (since C++23)
                                                                            (exposition
       only*)
              static constexpr auto /*dynamic-index-inv*/( rank_type i )
          noexcept;

So it’s private: — behind the velvet rope, no cap. It’s a template< class OtherIndexType >, it’s been around (since C++23), and it’s marked (exposition only*). The function itself is static constexpr auto /*dynamic-index-inv*/( rank_type i ) and it’s noexcept;.

Here’s the lore: it returns the number r such that in range [0, r + 1) there are exactly [0, i + 1) dynamic extents. And if i <= rank_dynamic() is false, the behavior is undefined — literally do not go there, bestie 😭.
