*Mandates:* `CallbackFn` satisfies both `invocable` and `destructible`.

``` cpp

stoppable-callback-for<CallbackFn, inplace_stop_token, Initializer>
|
| 37 |
+
```
|
| 38 |

|

is satisfied, then

|
| 41 |
+
``` cpp
|

```
|
| 44 |
+
|
| 45 |

is modeled. For an `inplace_stop_callback<CallbackFn>` object, the
|
| 46 |
+
exposition-only *`callback-fn`* member is its associated callback
|
| 47 |

function [[stoptoken.concepts]].
