Assigns contents to the contained value.
1)
Assigns by copying the state of
rhs
, as if by
any
(
rhs
)
.
swap
(
*
this
)
.
2)
Assigns by moving the state of
rhs
, as if by
any
(
std
::
move
(
rhs
)
)
.
swap
(
*
this
)
.
rhs
is left in a valid but unspecified state after the assignment.
3)
Assigns the type and value of
rhs
, as if by
any
(
std::
forward
<
ValueType
>
(
rhs
)
)
.
swap
(
*
this
)
. If
std::
is_copy_constructible
<
std::
decay_t
<
ValueType
>>
::
value
is
false
, the program is ill-formed. This overload participates in overload resolution only if
std::
decay_t
<
ValueType
>
is not the same type as
any
.
Template parameters
| ValueType | - | contained value type |
| Type requirements | ||
-
std::decay_t<ValueType>
must meet the requirements of
CopyConstructible
.

Parameters
| rhs | - | object whose contained value to assign |
Return value
* this
Exceptions
1,3)
Throws
bad_alloc
or any exception thrown by the constructor of the contained type. If an exception is thrown, there are no effects (strong exception guarantee).
