1)
Disposes the resource by calling the deleter with the underlying resource handle if the
unique_resource
owns it. The
unique_resource
does not own the resource after the call.
2)
Replaces the resource by calling
(1)
and then assigns the stored resource handle with
std::
forward
<
RR
>
(
r
)
if
std::
is_nothrow_assignable_v
<
RS, RR
>
is
true
, otherwise
std::
as_const
(
r
)
, where
RS
is the type of stored resource handle. The
unique_resource
owns the resource after the call.
If copy-assignment of the store resource handle throws an exception, calls
del_
(
r
)
, where
del
is the deleter object.
This overload participates in overload resolution only if the selected assignment expression assigning the stored resource handle is well-formed.
The program is ill-formed if
del_
(
r
)
is ill-formed.
The behavior is undefined if
del_
(
r
)
results in undefined behavior or throws an exception.
Parameters
| r | - | resource handle for a new resource to manage |
Return value
(none)
Exceptions
2)
Any exception thrown in assigning the stored resource handle.
Notes
The mechanism ensures no leaking of resources.
