std::hash(s...string_view,(3)

💖 NAME 💖

okay bestie, we're in the C++ Standard Libary manual — yes, that's the manual name, typo and all, and we're keeping it 💅 — and this is the std::hash(s...string_view,(3) page. The NAME block is literally this exact string twice with a - between them, no notes:

std::hash(std::experimental::string_view,std::experimental::wstring_view,
-
std::hash(std::experimental::string_view,std::experimental::wstring_view,

✨ Synopsis ✨

The synopsis says it's defined in header <experimental/string_view>, and then it drops the template specializations. Copying them exactly, including the (library fundamentals TS) bits, because we do not drop details in this house 🫶:

          Defined in header <experimental/string_view>
          template<> struct hash<std::experimental::string_view>;

          template<> struct hash<std::experimental::wstring_view>;    (library
       fundamentals
          template<> struct hash<std::experimental::u16string_view>;  TS)

          template<> struct hash<std::experimental::u32string_view>;

These are template specializations of std::hash for the various view classes for hashing views. that's the whole description, and it ate. 💅
