Cancellation

Cancellation is possible through a chained item's exposed task property, which returns a Task<T> that corresponds to the operation of the chain item AND all previous items in the chain. This task can then be cancelled using Swift's standard mechanism for cancellation.

You might think that the task of a chained item resulting from catch is never run, but tasks always runs regardless of success or failure of the chain of operations.

Chained items that are instantaneously evaluated (e.g. AsyncPlus.Result<T>) do not have a "task" that can be cancelled, but have a result or value instead.
