std::copyable(3)

💅 NAME 💅

okay bestie, welcome to std::copyable(3) from the C++ Standard Libary manual — yes, the header really says “Libary” and we are keeping that energy 💀.

• std::copyable — std::copyable — like, the concept herself. main character energy, no cap 👑

✨ Synopsis ✨

so this concept lives in the header <concepts>, and here’s the exact vibe:

          Defined in header <concepts>
          template< class T >

          concept copyable =
              std::copy_constructible<T> &&
              std::movable<T> &&                     (since C++20)
              std::assignable_from<T&, T&> &&
              std::assignable_from<T&, const T&> &&

              std::assignable_from<T&, const T>;

The concept copyable<T> specifies that T is a movable object type that can also be copied — that is, it supports copy construction and copy assignment. literally the whole point, fr fr 💖.

since C++20, bestie — put that in your notes ✨

• movable — specifies that an object of a type can be moved and swapped (C++20) (concept). lowkey the sibling concept you should also check out 🦋
