std::pmr::s...:do_is_equal(3)

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

💖 NAME 💖

okay so this page is std::pmr::s...:do_is_equal(3), and the manual it's chilling in is the C++ Standard Libary manual — yes, "Libary," that's the header spelling, and we are not fixing it, it's iconic now 💅.

The full name is std::pmr::synchronized_pool_resource::do_is_equal — and yep, the NAME line repeats it like it's hyping itself up: std::pmr::synchronized_pool_resource::do_is_equal. periodt. 🎀

✨ Synopsis ✨

virtual bool do_is_equal( const std::pmr::memory_resource& other )
(since C++17)
const noexcept;

This one is virtual, it's const, it's noexcept, and it's been here since C++17. The whole vibe: compare *this with other for identity — and memory allocated using a synchronized_pool_resource can only be deallocated using that same resource. no cap. 🫶

🫶 Return value 🫶

this == &other

Literal return value. That's it. That's the whole answer. 💖
