std::experi...::sentinel_t(3)

💖 NAME 💖

Okay so, welcome to the C++ Standard Libary manual page for std::experi...::sentinel_t(3) — aka the group-chat title for std::experimental::ranges::iterator_t, std::experimental::ranges::sentinel_t 🫶✨

The NAME is literally this whole combo, no cap: std::experimental::ranges::iterator_t,std::experimental::ranges::sentinel_t — and yes, the original page says the same thing twice, so we're keeping that energy. It's giving “name so nice they listed it twice” 💅.

✨ Synopsis ✨

Defined in header <experimental/ranges/range> — write that down, bestie, it's important 📝.

          template< class T >                                             (1)
       (ranges TS)
          using iterator_t = decltype(ranges::begin(std::declval<T&>()));
          template< class T >                                             (2)
       (ranges TS)
          using sentinel_t = decltype(ranges::end(std::declval<T&>()));

So here's the tea ☕: these two aliases are how you obtain the iterator and sentinel types of a range T. Literally that's the whole vibe — iterator_t and sentinel_t, both (ranges TS), both defined in that header, both doing their little decltype magic. Obsessed. 🌸
