std::swap(std::mdspan)(3)

💖 NAME 💖

okay so bestie, welcome to std::swap(std::mdspan)(3) from the C++ Standard Libary (yes, that spelling is straight from the header, don’t come for me 💀). The name is literally std::swap(std::mdspan) - std::swap(std::mdspan). Iconic. No notes. ✨

---

✨ Synopsis ✨

Defined in header <mdspan>:

friend constexpr void swap( mdspan& x, mdspan& y ) noexcept;

(since C++23) — okay so this is the friend function that overloads the std::swap algorithm for std::mdspan. It exchanges the state of x with that of y. Slay. 💅

Given ptr_, map_, and acc_ as exposition-only data members, it’s equivalent to:

std::swap(x.ptr_, y.ptr_);
std::swap(x.map_, y.map_);
std::swap(x.acc_, y.acc_);

---

🎀 Parameters 🎀

• x, y - mdspan objects whose states to swap

---

💅 Return value 💅

(none). Literally none. No return value, no drama. periodt. 🫶
