world.

This version of Boost is under active development. You are currently in the master branch. The current version is 1.89.0.
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.
boost::asio::awaitable<void> my_coroutine() { co_await boost::asio::this_coro::reset_cancellation_state( boost::asio::enable_partial_cancellation()); // ... }
The cancellation state is shared by all coroutines in the same "thread
of execution" that was created using co_spawn.
