Returns an awaitable object that may be used to reset the cancellation state of the current coroutine.

template<
    typename Filter>
constexpr unspecified reset_cancellation_state(
    Filter && filter);

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, std::forward<Filter>(filter)), into the current coroutine's cancellation state object.

Example

asio::awaitable<void> my_coroutine()
{
  co_await asio::this_coro::reset_cancellation_state(
      asio::enable_partial_cancellation());

  // ...
}

Remarks

The cancellation state is shared by all coroutines in the same "thread of execution" that was created using co_spawn.
