Defined in header <experimental/ranges/concepts>
template < class T > concept bool MoveConstructible =   Constructible<T, T> && ConvertibleTo<T, T>;		(ranges TS)

The concept MoveConstructible is satisfied if T is a reference type, or if it is an object type where an object of that type can constructed from an rvalue of that type in both direct- and copy-initialization contexts, with the usual semantics.

More precisely, if T is an object type, then MoveConstructible<T> is satisfied only if given

• rv, an rvalue of type T, and
• u2, a distinct object of type T equal to rv,

the following are true:

• After the definition T u = rv;, u is equal to u2;
• T{rv} is equal to u2; and
• If T is not const-qualified, then rv's resulting state (after the definition/expression is evaluated in either bullets above) is valid but unspecified; otherwise, it is unchanged.
