type Code ¶

type Code int

Code represents a stable fault code.

NB: All control plane errors should register their codes in the following block in order to avoid conflicts.

Also note that new codes should always be added at the bottom of their respective blocks. This ensures stability of fault codes over time.

	Unknown Code = iota
