32.3.4.1 General [stoptoken.general]
The class stop_token models the concept stoppable_token.
It shares ownership of its stop state, if any, with its associated stop_source object ([stopsource]) and any stop_token objects to which it compares equal.
namespace std {class stop_token {public:templateusing callback_type = stop_callback;
stop_token() noexcept = default; // [stoptoken.mem], member functionsvoid swap(stop_token&) noexcept; bool stop_requested() const noexcept; bool stop_possible() const noexcept; bool operator==(const stop_token& rhs) noexcept = default; private: shared_ptr<unspecified> stop-state; // exposition only};}
stop-state refers to the stop_token's associated stop state.
A stop_token object is disengaged when stop-state is empty.
