func (o *Snapshotter) Stat(ctx context.Context, key string) (snapshot.Info, error)

Stat returns the info for an active or committed snapshot by name or key.

Should be used for parent resolution, existence checks and to discern the kind of snapshot.

func (*Snapshotter) Usage

func (o *Snapshotter) Usage(ctx context.Context, key string) (snapshot.Usage, error)

func (*Snapshotter) View

func (o *Snapshotter) View(ctx context.Context, key, parent string) ([]mount.Mount, error)

func (*Snapshotter) Walk

func (o *Snapshotter) Walk(ctx context.Context, fn func(context.Context, snapshot.Info) error) error

Walk the committed snapshots.
