Variables

var (
	// IndexPath is the path to the index.json file
	IndexPath = filepath.Join(ImagesDir, IndexJSON)
	// ImagesBlobsDir is the path to the directory containing the image blobs in the OCI package.
	ImagesBlobsDir = filepath.Join(ImagesDir, "blobs", "sha256")

)

var ErrNotLoaded = fmt.Errorf("not loaded")

ErrNotLoaded is returned when a path is not loaded.

Functions

func IsNotLoaded

func IsNotLoaded(err error) bool
