[stoptoken.inplace]

The class inplace_stop_token models the concept stoppable_token .

It references the stop state of its associated inplace_stop_source object ([stopsource.inplace]), if any.

namespace std { class inplace_stop_token { public: template<class CallbackFn> using callback_type = inplace_stop_callback<CallbackFn>; inplace_stop_token() = default; bool operator=(const inplace_stop_token&) const = default; / [stoptoken.inplace.mem], member functions bool stop_requested() const noexcept; bool stop_possible() const noexcept; void swap(inplace_stop_token&) noexcept; private: const inplace_stop_source* stop-source = nullptr; / exposition only }; }

🔗

void swap(inplace_stop_token& rhs) noexcept;

Effects: Exchanges the values of stop-source and rhs.stop-source.

🔗

bool stop_requested() const noexcept;

Effects: Equivalent to: return stop-source != nullptr && stop-source->stop_requested();

[Note 1:

As specified in [basic.life], the behavior of stop_requested is undefined unless the call strongly happens before the start of the destructor of the associated inplace_stop_source object, if any.

— end note]

🔗

stop_possible() const noexcept;

[Note 2:

As specified in [basic.stc.general], the behavior of stop_possible is implementation-defined unless the call strongly happens before the end of the storage duration of the associated inplace_stop_source object, if any.
