If T is an object type, then let rv be an rvalue of typeT and u2 a distinct object of type T equal torv.

T models move_constructible only if

• (1.1)

  After the definition T u = rv;, u is equal to u2.

• (1.2)

  T(rv) is equal to u2.

• (1.3)

  If T is not const, rv's resulting state is valid but unspecified ([lib.types.movedfrom]); otherwise, it is unchanged.
