std::copyable

From cppreference.com
< cpp‎ | concepts
Defined in header <concepts>
template <class T>

concept copyable =
  std::copy_constructible<T> &&
  std::movable<T> &&

  std::assignable_from<T&, const T&>;
(since C++20)

The concept copyable<T> specifies that T is an movable object type that can also copied (that is, it supports copy construction and copy assignment).

[edit] Notes

It is intended that copyable<T> also requires std::assignable_from<T&, const T> (assignment from const rvalue) and std::assignable_from<T&, T&> (assignment from non-const lvalue) to be satisfied.
