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

okay bestie, welcome to the C++ Standard Libary manual page for std::pmr::monotonic_buffer_resource::do_is_equal 💖 the header shortens it to std::pmr::m...do_is_equal(3) because even manpage titles need a little nap.

🌸 NAME 🌸

This page is literally about std::pmr::monotonic_buffer_resource::do_is_equal — and yes, std::pmr::monotonic_buffer_resource::do_is_equal again, because the NAME section said it twice and I respect that 💅.

✨ Synopsis ✨

virtual bool do_is_equal( const std::pmr::memory_resource& other )
const noexcept;

(since C++17) bestie, she’s been here since then ✨

Compare *this with other for identity — memory allocated using a monotonic_buffer_resource can only be deallocated using that same resource. no cap, that’s the whole vibe 🫶

💅 Return value 💅

The return value is literally:

this == &other

that’s it, that’s the whole serve 😭

😭 Defect report 😭

The following behavior-changing defect reports were applied retroactively to previously published C++ standards. yes, the lore goes back 👑

• DR: LWG 3000
• Applied to: C++17
• Behavior as published: unnecessary dynamic_cast was performed
• Correct behavior: removed

👑 See also 👑

• do_is_equal — compare for equality with another memory_resource [virtual] (virtual private member function of std::pmr::memory_resource) 🦋
