public final class LensSubject<A, B>: SubjectType

Enables reactive read and copy-on-write access for an entity’s property in a datastructure. Applies a given Lens to a subject.


                    
                    
                    init(initial:source:target:lens:)

Parameter

Parameter initial: The initial value to be used.

Parameter

Parameter source: The observable that emits the data structure.

Parameter

Parameter target: The observer for data structure.
