std::ranges...ew::iterator(3)

💖 NAME 💖

okay so bestie, welcome to the std::ranges...ew::iterator(3) page from the C++ Standard Libary (that spelling is canon, don't come for me 💀). The actual name is std::ranges::slide_view::iterator — and the page literally says std::ranges::slide_view::iterator - std::ranges::slide_view::iterator, which is highkey iconic of it.

---

🦋 Synopsis 🦋

template< bool Const >  (since C++23)
class /*iterator*/      (exposition only*)

This is the return type of slide_view::begin, and of slide_view::end when the underlying view V is a common_range. no cap, that's the whole vibe.

The type /*iterator*/<true> is returned by the const-qualified overloads. The type /*iterator*/<false> is returned by the non-const-qualified overloads. slay, const correctness 💅.

🎀 Member types 🎀

here's the member-type tea, bestie ☕:

• Base (private) — const V if Const is true, otherwise V. (exposition-only member type*)
• iterator_category — std::input_iterator_tag.
• iterator_concept —
  • std::random_access_iterator_tag, if Base models random_access_range. Otherwise,
  • std::bidirectional_iterator_tag, if Base models bidirectional_range. Otherwise,
  • std::forward_iterator_tag.
• value_type — decltype(views::counted(current_, n_)).
• difference_type — ranges::range_difference_t<Base>.

---

🧺 Data members 🧺

these are the private little data gremlins, and yes they're exposition-only 👀:

• current_ (private) — ranges::iterator_t<Base>, holds an iterator to the first underlying element of the current window in slide_view (exposition-only member object*).
• last_ele_ (private) (optional) — ranges::iterator_t<Base>, holds an iterator to the one-past-end underlying element of the current window in slide_view. Present only if Base models /*slide-caches-first*/. (exposition-only member object*)
• n_ (private) — ranges::range_difference_t<Base>, holds the window width of slide_view. (exposition-only member object*)

---

✨ Member functions ✨

• constructor — constructs an iterator (C++23, public member function).
• operator* — accesses the element (C++23, public member function).
• operator[] — accesses an element by index (C++23, public member function).
• operator++, operator++(int), operator--, operator--(int), operator+=, operator-= — advances or decrements the underlying iterators (C++23, public member function).

---

🌈 Non-member functions 🌈

• operator==, operator<, operator>, operator<=, operator>=, operator<=> — compares the underlying iterators (C++23, function).
• operator+, operator- — performs iterator arithmetic (C++23, function).

not me leaving this section empty, but that's literally what the page says 😭.
