public class RVP_Cocoa_SDK_Payload
This is a special class for representing the payload as an atomic object. It encapsulates the type and the payload, as a Data object.
Expressing it as a class gives us a couple of things: 1) It allows us to keep it as a reference, as opposed to a copy, and 2) It allows us to easily extend the class with data interpretation.
The payload, as a Data object.
public var payloadData: Data?
The payload MIME type, as a String.
public var payloadType: String
