    func cancel()


    Task cancellation is cooperative: a task that supports cancellation checks whether it has been canceled at various points during its work.

    Calling this method on a task that doesn’t support cancellation has no effect. Likewise, if the task has already run past the last point where it would stop early, calling this method has no effect.
