std::movable(3)

💖 std::movable(3) 💖

okay so bestie, this is page std::movable(3) from the C++ Standard Libary manual, and we're doing concepts today. no cap. 💅

🎀 NAME 🎀

std::movable - std::movable

that's the name. iconic, honestly. ✨

🌈 Synopsis 🌈

Defined in header <concepts> — yes bestie, that's where it lives. 🦋

Defined in header <concepts>
template< class T >

concept movable =
    std::is_object_v<T> &&          (since C++20)
    std::move_constructible<T> &&
    std::assignable_from<T&, T> &&

    std::swappable<T>;

so what is this actually saying? The concept movable<T> specifies that T is an object type that can be moved — that is, it can be move constructed, it can be move assigned, and lvalues of type T can be swapped. literally the whole "can I move this around?" vibe check. 😭🔥
