Variables

var ErrInProgress = errors.New("in progress")

ErrInProgress is returned when a generation is in progress.

var ErrNotCreated = errors.New("not created")

ErrNotCreated is returned when a key is not created.

var ErrNotFound = errors.New("not found")

ErrNotFound is returned when a generation is not found.

var ErrNotInProgress = errors.New("not in progress")

ErrNotInProgress is returned when a generation is not in progress.
