Returns an awaitable object that may be used to reset the cancellation state of the current coroutine.
constexpr unspecified reset_cancellation_state();
Let P be the cancellation slot associated with the current
coroutine's co\_spawn completion handler. Assigns a new cancellation_state
object S, constructed as S(P), into the current
coroutine's cancellation state object.
boost::asio::awaitable<void> my_coroutine()
{
co_await boost::asio::this_coro::reset_cancellation_state();
// ...
}
The cancellation state is shared by all coroutines in the same "thread
of execution" that was created using co_spawn.
