std::ranges..._view::base(3)

💅 std::ranges..._view::base(3) 💅

okay so welcome to the C++ Standard Libary manual page for std::ranges::common_view::base — yes bestie, that's the manual name, folded in right here instead of copy-pasting the header line like a NPC. This page is lowkey all about std::ranges::common_view::base, and it's giving very specific C++20 energy. 🦋

---

🌸 NAME 🌸

std::ranges::common_view::base - std::ranges::common_view::base

---

✨ Synopsis ✨

This bad boy returns a copy of the underlying view — that's the whole plot. The synopsis is giving two overloads, both since C++20:

          constexpr V base() const& requires std::copy_constructible<V>; (1)
       (since C++20)
          constexpr V base() &&;                                         (2)
       (since C++20)

So real talk:

1. (1) copy constructs the result from the underlying view.
2. (2) move constructs the result from the underlying view.

🌼 Parameters 🌼

(none) — literally zero arguments, bestie. Nada. The parameter list is empty and thriving. 🫶

💖 Return value 💖

A copy of the underlying view. That's it. That's the tea. 👑

🎀 Example 🎀

       // Run this code

        #include <iostream>
        #include <ranges>
        #include <string>

        int main()
        {
            std::string str { "C++20" };
            auto view = std::views::common(str);

            std::string copy_of_str = view.base();
            std::cout << "copy of str: [" << copy_of_str << "]\n";
            std::cout << "view.base(): [" << view.base() << "]\n";

            std::string move_str = std::move(view.base());
            std::cout << "moved str:   [" << move_str << "]\n";
            std::cout << "view.base(): [" << view.base() << "]\n"; //
       unspecified
        }

bestie notice the last line is marked // unspecified — that means exactly what it says: unspecified. Do not build your whole personality on that final output, okay? 😭💀

🌈 Possible output 🌈

        copy of str: [C++20]
        view.base(): [C++20]
        moved str:   [C++20]
        view.base(): []

okay that's the whole page, periodt! This manual page came from http://cppreference.com, dated 2024.06.10, and its footer tag is std::ranges..._view::base(3) — catch you in the next one, bestie 💖🎀
