RSDNavigationRule

public protocol RSDNavigationRule

Define the navigation rule as a protocol to allow for protocol-oriented extension (multiple inheritance). Currently defined usage is to allow the RSDConditionalStepNavigator to check if a step has a navigation rule and apply as necessary.


                    
                    
                    nextStepIdentifier(with:isPeeking:)

Identifier for the next step to navigate to based on the current task result and the conditional rule associated with this task.
