public protocol LibraryAttributes : Decodable, Encodable

A type that holds the value of library attributes.

Use the LibraryAttributes protocol to provide a library attributes to a class or value type. For example, you could define a Show type with a library status property that is stable across your app and your app’s database storage. You could use the library status property to identify a particular show’s library status even if other data fields change, such as the show’s title.
