namespace std {templateclass inplace_stop_callback {public:using callback_type = CallbackFn; // [stopcallback.inplace.cons], constructors and destructortemplateexplicit inplace_stop_callback(inplace_stop_token st, Initializer&& init)noexcept(is_nothrow_constructible_v<CallbackFn, Initializer>); ~inplace_stop_callback();

Mandates: CallbackFn satisfies bothinvocable and destructible.
Remarks: For a type Initializer, ifstoppable-callback-for<CallbackFn, inplace_stop_token, Initializer> is satisfied, thenstoppable-callback-for<CallbackFn, inplace_stop_token, Initializer> is modeled.
For an inplace_stop_callback object, the exposition-only callback-fn member is its associated callback function ([stoptoken.concepts]).
