32.3.10.1 General [stopcallback.inplace.general]

namespace std { template<class CallbackFn> class inplace_stop_callback { public: using callback_type = CallbackFn;template<class Initializer> explicit inplace_stop_callback(inplace_stop_token st, Initializer&& init) noexcept(is_nothrow_constructible_v<CallbackFn, Initializer>);~inplace_stop_callback(); inplace_stop_callback(inplace_stop_callback&&) = delete; inplace_stop_callback(const inplace_stop_callback&) = delete; inplace_stop_callback& operator=(inplace_stop_callback&&) = delete; inplace_stop_callback& operator=(const inplace_stop_callback&) = delete;private: CallbackFn callback-fn; };template<class CallbackFn> inplace_stop_callback(inplace_stop_token, CallbackFn) -> inplace_stop_callback<CallbackFn>;}

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<CallbackFn> object, the exposition-only callback-fn member is its associated callback function ([stoptoken.concepts]).
