How to get enum case name in Swift from within CustomStringConvertible implementation?

I have an enum that looks like this:

enum IntteruptCause: UInt8 {
    case userDisplayDisengage = 0
    case userSteeringWheelDisengage = 1
    case positionDropout = 2
}

Currently the output from print() will give me the case name.

I would like to implment CustomStringConvertible and have it produce both the case name and the rawValue, e.g. the string User_Steering_Wheel_Disengage (1).

When I implement var description: String I have easy access to rawValue but I cannot seem to find out how to get the enum case name. Normally I would do String(describing: value) but that would create an infinite recursion if used in description implementation.

Is it possible to get the enum case name from within the description implementation?

I think hardcoding them is the best way there is at the moment... – Sweeper Apr 06 '20 at 10:02
Unrelated to your question, but you should conform to the Swift naming convention, which is lowerCamelCase for variables, including enum cases. – Dávid Pásztor Apr 06 '20 at 10:26
