Enum MetadataBasis 

pub enum MetadataBasis {
    Genesis,
    Manifest(BasisManifest),
}

The materialized starting point every read and flush builds on.

Variants

Genesis

The built-in genesis state: one root-inode row at sequence zero, synthesized rather than loaded. A created namespace reads from this until its first flush publishes a manifest.

Manifest(BasisManifest)

A manifest object, owned by this namespace or — while the head still authorizes it — by the fork source.

Implementations

impl MetadataBasis

pub fn manifest(&self) -> Option<&BasisManifest>

pub fn manifest_id(&self) -> ManifestId

Logical position this basis sits at. Genesis is position zero: the namespace’s first published manifest is one past it.

pub fn is_owned_by(&self, namespace_id: &NamespaceId) -> bool

Whether the basis is a manifest this namespace itself published, so its own metadata/root.json exists.
