std::experi...ges::tagged)(3)

💖 std::experimental::ranges::swap(ranges::tagged) 💖

okay bestie, this page is from the C++ Standard Libary manual (yes, that spelling is literally in the source, no cap), and we're talking about the ranges::tagged swap situation. it's giving niche-but-iconic 🎀

✨ NAME ✨

std::experimental::ranges::swap(ranges::tagged) - std::experimental::ranges::swap(ranges::tagged)

✨ Synopsis ✨

          friend constexpr void swap( tagged& lhs, tagged& rhs )
          noexcept(noexcept(lhs.swap(rhs)))
              requires Swappable<Base>;

Swap the contents of *this and rhs, as if by lhs.swap(rhs);.

This function is not visible to ordinary unqualified or qualified lookup, and it can only be found by argument-dependent lookup when tagged is an associated class of the arguments. lowkey hidden-friend magic ✨

💅 Notes 💅

Unlike most non-member swaps in the standard library, this swap is a hidden friend function declared in the body of tagged, not a function template. the tagged in the function declaration is the injected-class-name. slay, C++ linguistics 💀
