func LegacyWriteManifestToStore added in v0.13.0

func LegacyWriteManifestToStore(ctx context.Context, store storage.Store, txn storage.Transaction, manifest Manifest) error

LegacyWriteManifestToStore will write the bundle manifest to the older single (unnamed) bundle manifest location. Deprecated: Use WriteManifestToStore and named bundles instead.

func ManifestStoragePath added in v0.13.0

func ManifestStoragePath(name string) storage.Path

ManifestStoragePath is the storage path used for the given named bundle manifest.

func ReadBundleNamesFromStore added in v0.13.0

func ReadBundleNamesFromStore(ctx context.Context, store storage.Store, txn storage.Transaction) ([]string, error)

ReadBundleNamesFromStore will return a list of bundle names which have had their metadata stored.

func ReadBundleRevisionFromStore added in v0.13.0

func ReadBundleRevisionFromStore(ctx context.Context, store storage.Store, txn storage.Transaction, name string) (string, error)
