std::ranges..._view::base(3) C++ Standard Libary std::ranges..._view::base(3) NAME std::ranges::common_view::base - std::ranges::common_view::base Synopsis constexpr V base() const& requires std::copy_constructible<V>; (1) (since C++20) constexpr V base() &&; (2) (since C++20) Returns a copy of the underlying view. 1) Copy constructs the result from the underlying view. 2) Move constructs the result from the underlying view. Parameters (none) Return value A copy of the underlying view. 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"; // unspeci- fied } Possible output: copy of str: [C++20] view.base(): [C++20] moved str: [C++20] view.base(): [] http://cppreference.com 2024.06.10 std::ranges..._view::base(3)
