Fields

digest: String

Manifest digest (sha256:hex). Canonical snapshot identity.

name: Option<String>

Convenience name (unique when present). NULL for digest-only entries.

parent_digest: Option<String>

Manifest digest of the parent snapshot, or NULL for a root.

scope: String

Snapshot payload scope (disk today, resumable in the future).

state_kind: String

Closed descriptor state discriminant (file or checkpoint).

image_ref: String

Human-readable image reference.

image_manifest_digest: String

OCI manifest digest of the image.

format: Option<String>

On-disk format of the upper layer (raw or qcow2).

fstype: Option<String>

Filesystem type inside the upper (e.g. ext4).

checkpoint_manifest_digest: Option<String>

Checkpoint-manifest digest for checkpoint state.

artifact_path: String

Absolute path to the artifact directory on this host.

size_bytes: Option<i64>

Apparent size of the upper file in bytes.

locality: String

Locality of the state closure (embedded or linked).

storage_binding_id: Option<String>

Host-local storage/provider binding identifier.

availability: String

Rebuildable closure availability projection.

migration_state: String

Artifact migration status projection.

migration_error_code: Option<String>

Stable migration failure code when blocked.

created_at: DateTime

Snapshot creation time (from manifest).

indexed_at: DateTime

When this row was inserted/refreshed.

child_count: i32

Number of indexed snapshots whose parent_digest == self.digest.
