func NewLabeledStore(root string, ls LabelStore) (content.Store, error)
NewLabeledStore returns a new content store using the provided label store
Note: content stores which are used underneath a metadata store may not require labels and should use `NewStore`. `NewLabeledStore` is primarily useful for tests or standalone implementations.
func NewStore(root string) (content.Store, error)
NewStore returns a local content store
func OpenReader(p string) (content.ReaderAt, error)
OpenReader creates ReaderAt from a file
LabelStore is used to store mutable labels for digests
type LabelStore interface {
// Get returns all the labels for the given digest
Get(digest.Digest) (map[string]string, error)
// Set sets all the labels for a given digest
Set(digest.Digest, map[string]string) error
// Update replaces the given labels for a digest,
// a key with an empty value removes a label.
Update(digest.Digest, map[string]string) (map[string]string, error)
}
