std::ranges...perator++,--(3)

💖 NAME 💖

okay so bestie, we're on the std::ranges::chunk_by_view::iterator::operator++,-- page from the C++ Standard Libary ✨ and the name situation is literally:

• std::ranges::chunk_by_view::iterator::operator++,-- — std::ranges::chunk_by_view::iterator::operator++,--

no cap, that's the whole name vibe 💅

✨ Synopsis ✨

here's the icon lineup, all since C++23 🎀

• constexpr /*iterator*/& operator++(); — (1) (since C++23)
• constexpr /*iterator*/ operator++(int); — (2) (since C++23)
• constexpr /*iterator*/& operator--() requires ranges::bidirectional_range<V>; — (3) (since C++23)
• constexpr /*iterator*/ operator--(int) requires ranges::bidirectional_range<V>; — (4) (since C++23)

on the page it's laid out like this, lowkey:

constexpr /*iterator*/& operator++();

(1) (since C++23)

constexpr /*iterator*/ operator++(int);

(2) (since C++23)

constexpr /*iterator*/& operator--() requires
  ranges::bidirectional_range<V>;

(3) (since C++23)

constexpr /*iterator*/ operator--(int) requires
  ranges::bidirectional_range<V>;

(4) (since C++23)

Increments or decrements the iterator. periodt 💫

Let parent_, current_, and next_ be the appropriate underlying (exposition-only) data-members of iterator.

Let find-next and find-prev be appropriate (exposition-only) member functions of ranges::chunk_by_view.

1. operator++() (1) — Equivalent to:

current_ = next_;
next_ = parent_->/*find-next*/(current_);
return *this;

🚨 The behavior is undefined if before the call to this operator current_ is equal to next_. like bestie, that's the danger zone, do not go there 💀

2. operator++(int) (2) — Equivalent to: auto tmp = *this; ++*this; return tmp;
3. operator--() (3) — Equivalent to:

next_ = current_;
current_ = parent_->/*find-prev*/(next_);
return *this;

4. operator--(int) (4) — Equivalent to: auto tmp = *this; --*this; return tmp;

🎀 Return value 🎀

• 1,3) *this
• 2,4) a copy of *this that was made before the change.

and that's the whole page, bestie 💖 lil sign-off kiss: source/version is http://cppreference.com, date is 2024.06.10, and the page tag is std::ranges...perator++,--(3) 🌸 mwah 🫶
