std::experi...iew::rbegin,(3)

🌸 NAME 🌸

okay so bestie, this page is literally about std::experimental::basic_string_view::rbegin — and yeah the name line in the original is a whole mess, it says std::experimental::basic_string_view::rbegin, - and then std::experimental::basic_string_view::rbegin, again, so it's giving "said it twice for emphasis" energy 💅 (it's from the C++ Standard Library manual family, if you were wondering where we're at).

---

✨ Synopsis ✨

here's the whole thing, no notes, exactly as written:

constexpr const_reverse_iterator rbegin() const noexcept;  (library
fundamentals TS)
constexpr const_reverse_iterator crbegin() const           (library
fundamentals TS)
noexcept;

both of these are the library fundamentals TS version, just so we're clear 🫶

so what does it actually do? it returns a reverse iterator pointing at the first character of the reversed view — which, yes, is the same thing as the last character of the non-reversed view. the way that works is honestly iconic: you flip the direction, and suddenly "first" means "last." main character energy 🔥

also there's a little diagram on the page, it's called range-rbegin-rend.svg — that's the visual, go look at it if you're a visual learner 🦋

🎀 Parameters 🎀

• (none) — yeah, nothing. no parameters. she takes nothing. periodt 💀

---

⭐ Return value ⭐

a const_reverse_iterator to the first character ✨

---

🌈 Complexity 🌈

Constant. like, constant. it's not doing a loop, bestie, it's just vibing in O(1) 💖

🦋 See also 🦋

• rend — returns a reverse iterator to the end
• crend — (public member function)

ok lowkey quick reminder: this is the TS (std::experimental) version of things, so don't go acting like it's the fully standardized one, iykyk 🙈

and that's the page!! fr fr, it's short but she ate. this was the std::experi...iew::rbegin,(3) page off http://cppreference.com, dated 2024.06.10 — mwah, go reverse some iterators bestie 🧚💜🌸
