Types

type Backend

type Backend interface {
	Get(id digest.Digest) ([]byte, error)
	Set(data []byte) (digest.Digest, error)
	Delete(id digest.Digest) error
	ListImages() ([][]byte, error)
	SetMetadata(id digest.Digest, key string, data []byte) error
	GetMetadata(id digest.Digest, key string) ([]byte, error)
	DeleteMetadata(id digest.Digest, key string) error
	LayerDBDir(digest digest.Digest) string
	LayerDataDir(digest digest.Digest) string
	// contains filtered or unexported methods
}

Backend is a service for image/layer read and write. is majorly used by layer store. Avoid invoking backend by others as possible as we can.
