Manifest state: the atomic checkpoint of the database.

This raw structure is exposed for explicit diagnostic introspection through DatabaseEngine::manifest() and manifest::load_manifest_readonly(). Ordinary graph APIs use named labels and edge labels and do not accept these internal numeric token IDs as inputs.

Fields

version: u32

label_token_schema_version: u32

Named node-label / edge-label token schema marker.

node_label_tokens: BTreeMap<String, u32>

DB-scoped node-label catalog: public label -> internal label_id.

edge_label_tokens: BTreeMap<String, u32>

DB-scoped edge-label catalog: public edge label -> internal label_id.

next_node_label_id: u32

Next node-label token ID to allocate.

next_edge_label_id: u32

Next edge-label token ID to allocate.

segments: Vec<SegmentInfo>

next_node_id: u64

next_edge_id: u64

dense_vector: Option<DenseVectorConfig>

DB-scoped dense vector configuration.

prune_policies: BTreeMap<String, PrunePolicy>

Named prune policies applied automatically during compaction. Absent from older manifests; defaults to empty.

next_engine_seq: u64

Next engine sequence number to assign. Persisted across flush/reopen.

next_wal_generation_id: u64

Next WAL generation ID to allocate. Monotonically increasing.

active_wal_generation_id: u64

WAL generation ID of the currently active (writable) WAL file.

pending_flush_epochs: Vec<FlushEpochMeta>

Flush epochs that are in-flight (frozen or published but not yet retired).

secondary_indexes: Vec<SecondaryIndexManifestEntry>

Optional secondary index declarations.

next_secondary_index_id: u64

Next declaration ID to allocate.
