New error protocol

[Casperhr]

enum MyError: AbortError {
case missingUsername(metadata: Node?)
case missingEmail(metadata: Node?)

var code: Int {
    switch self {
        case .missingUsername: return 401
        case .missingEmail: return 402
    }
}

var status: Status {
    return .badRequest
}

var message: String {
    switch self {
        case .missingUsername: return "Missing username"
        case .missingEmail: return "Missing email"
    }
}

var metadata: Node? {
    switch self {
        case missingUsername(metadata: let node): return node
        case missingEmail(metadata: let node): return node
    }
}

}

Or if you don't want a different default case for each one you could instead do something like:

    case error(message: String, code: Int, status: Status, metadata: Node?)
}

Then for each of the values required for the protocol just extracted the associated values within the enum and return them

The main downside of that is if you want to call the same error multiple times you now have to copy paste all of those values

Instead of updating them in one place
