template <class T>

concept bool Copyable =
  ranges::CopyConstructible<T> &&
  ranges::Movable<T> &&

  ranges::Assignable<T&, const T&>;
(ranges TS)

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 ranges::Assignable<T&, const T> (assignment from const rvalue) and ranges::Assignable<T&, T&> (assignment from non-const lvalue) to be satisfied.

[edit] See also

specifies that an object of a type can be moved and swapped
