Cancelable

Represents an object that can be marked as canceled.

This is typically used by events whose handlers may choose to interrupt or prevent further processing. When an event implementing Cancelable is posted via Bus.post, its canceled flag is interpreted according to the selected CancelMode:

• With CancelMode.IGNORE, the flag is ignored by the bus and all handlers run.

• With CancelMode.RESPECT, canceled events are delivered only to handlers that opt in via EventHandler.runIfCanceled.

• With CancelMode.ENFORCE, dispatch stops as soon as the event is observed in a canceled state.

A default implementation is provided via the companion object's invoke operator.
