std::extents::index-cast(3)

💖 std::extents::index-cast(3) 💖

okay so bestie, welcome to std::extents::index-cast(3) from the C++ Standard Libary — that's the manual name, and yes it's spelled exactly like that. This page is short but it's giving C++23 template energy, so let's go ✨🫶

🌸 NAME 🌸

• std::extents::index-cast — std::extents::index-cast 💅

---

✨ Synopsis ✨

No cap, the whole synopsis is this exact code:

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

It casts the index i in type OtherIndexType into a certain integral type. It is equivalent to:

• return i;, if OtherIndexType is an integral type other than bool, and
• return static_cast<index_type>(i); otherwise.

lowkey important: the exposition only* bit stays exactly as written, bestie. Don't come for me. 🙈

🍓 Parameters 🍓

• i — the index to be cast. That's it, that's the parameter. 🫶

👑 Return value 👑

Cast index. Yep, literally the cast index. Slay.
