Defined in header <experimental/ranges/concepts>
template< class T > concept bool Copyable =     CopyConstructible<T> &&     Movable<T> &&     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).

Notes

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

Movable

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