std::experi..._view::rend,(3)

📦 version 2024.07.05, in nixpkgs unstable, opensuse-leap 16.0

🌸 NAME 🌸

okay bestie, welcome to the <pink>std::experi..._view::rend,(3)</pink> page — that's the title, and the manual up top is C++ Standard Libary (yes, literally spelled like that in the header, no cap 💀). The NAME line is exactly this:

  • std::experimental::basic_string_view::rend, - std::experimental::basic_string_view::rend,

✨ Synopsis ✨

two overloads, both from the library fundamentals TS, and they are giving constexpr + noexcept energy:

constexpr const_reverse_iterator rend() const noexcept;   (library fundamentals TS)
constexpr const_reverse_iterator crend() const noexcept;  (library fundamentals TS)

so what do they do? okay so: rend returns a reverse iterator to the character following the last character of the reversed view. it corresponds to the character preceding the first character of the non-reversed view. that character is literally acting as a placeholder, and attempting to access it results in undefined behavior.

🚨 undefined behavior alert, bestie: that placeholder character is not for touching. attempting to access it is undefined behavior, periodt.

there's also a lil visual moment here: range-rbegin-rend.svg 🦋

🧸 Parameters 🧸

(none) — no arguments, no stress, no drama 💅

🎁 Return value 🎁

a const_reverse_iterator to the character following the last character. that's the whole vibe.

⚡ Complexity ⚡

Constant. iconic, effortless, no notes 👑
