boost::capy::run_async

Asynchronously launch a lazy task with stop token support.

Synopsis

template<Executor Ex>
[[nodiscard]]
auto
run_async(
    Ex ex,
    std::stop_token st);

The stop token is propagated to the task, enabling cooperative cancellation. With no handlers, the result is discarded and exceptions are rethrown.

The wrapper may be called from any thread where the executor schedules work.

std::stop_source source;
run_async(ex, source.get_token())(cancellable_task());
// Later: source.request_stop();

A wrapper that accepts a task<T> for immediate execution.
