Defined in header <concepts>
template < class T > concept Movable =   std::is_object_v<T> &&   std::MoveConstructible<T> &&   std::Assignable<T&, T> &&   std::Swappable<T>;		(since C++20)

The concept Movable<T> specifies that T is an object type that can moved (that is, it can be move constructed, move assigned, and lvalues of type T can be swapped).
