``` cpp
|
| 4 |
+
any& operator=(const any& rhs);
|
| 5 |
+
```
|
| 6 |
+
|
| 7 |
+
*Effects:* As if by `any(rhs).swap(*this)`. No effects if an exception
|
| 8 |
+
is thrown.
|
| 9 |
+
|
| 10 |
+
*Returns:* `*this`.
|
| 11 |
+
|
| 12 |
+
*Throws:* Any exceptions arising from the copy constructor for the
|
| 13 |
+
contained value.
|
| 14 |
+
|
| 15 |
+
``` cpp
|
| 16 |
+
any& operator=(any&& rhs) noexcept;
|
| 17 |
+
```
|
| 18 |
+
|
| 19 |
+
*Effects:* As if by `any(std::move(rhs)).swap(*this)`.
|
| 20 |
+
|
| 21 |
+
*Returns:* `*this`.
|
| 22 |
+
|
| 23 |
+
*Postconditions:* The state of `*this` is equivalent to the original
|
| 24 |
+
state of `rhs` and `rhs` is left in a valid but otherwise unspecified
|
| 25 |
+
state.
|
| 26 |
+
|
| 27 |
+
``` cpp
|
| 28 |
+
template<class T>
|
| 29 |
+
any& operator=(T&& rhs);
|
| 30 |
+
```
|
| 31 |
+
|
| 32 |
+
Let `VT` be `decay_t<T>`.
|
| 33 |
+
|
| 34 |
+
*Requires:* `VT` shall satisfy the `CopyConstructible` requirements.
|
| 35 |
+
|
| 36 |
+
*Effects:* Constructs an object `tmp` of type `any` that contains an
|
| 37 |
+
object of type `VT` direct-initialized with `std::forward<T>(rhs)`, and
|
| 38 |
+
`tmp.swap(*this)`. No effects if an exception is thrown.
|
| 39 |
+
|
| 40 |
+
*Returns:* `*this`.
|
| 41 |
+
|
| 42 |
+
*Remarks:* This operator shall not participate in overload resolution
|
| 43 |
+
unless `VT` is not the same type as `any` and
|
| 44 |
+
`is_copy_constructible_v<VT>` is `true`.
|
| 45 |
+
|
| 46 |
+
*Throws:* Any exception thrown by the selected constructor of `VT`.
