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