Defined in header
<concepts>
template< class T >
(since C++20)
concept copyable =
std::copy_constructible <T> &&
std::movable <T> &&
std::assignable_from <T&, 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).
