All events conforming to an error protocol type have the following properties:
- success: boolean: True if the command was successful, otherwise false.
- code: integer: 0 if the command was successful, otherwise an internal value. If the OS does not provide one, this will be -1.
- error: optional string: undefined if the command was successful, otherwise a concatenation of the localized String and userinfo's message if it exists.
