Module occurrence 

Occurrence rows, headers and property/embedding metadata.

Structs

EmbeddingBinding

One canonical source -> Space association carrying the exact value hash at bind time. Eligible only while that hash remains current.

EmbeddingSpaceInfo

Immutable metadata for an embedding space.

OccValue

A decoded occurrence row value.

OccurrenceRow

One property occurrence of a record or relationship. Its identity is (owner_kind, owner_ord, property_id, elem); the canonical row is keyed by exactly that (keys::occ_key, DC11).

PropertyDefinition

A typed property definition within a family.

PropertyFamily

A normalized property family, scoped to records or relationships.

RecordHeader

Durable header for a record.

RelationshipHeader

Durable header for a relationship.

Enums

BindingStatus

Lifecycle status of an embedding binding.

OccurrenceValue

ExplicitNull is a payload-free occurrence state, never a domain type.

Similarity

Immutable vector-space contract bound through stable aliases.

Constants

OCC_FLAG_ARRAY

Occurrence row flag: the occurrence is an element of an array property.

OCC_STATE_EMPTY_ARRAY

Occurrence row state: the zero-element array marker.

OCC_STATE_NULL

Occurrence row state: explicit null.

Functions

decode_occ_value

Decode an occurrence row value written by encode_occ_value.

encode_occ_value

Encode an occurrence row value: flags || state || payload, where state is OCC_STATE_NULL, OCC_STATE_EMPTY_ARRAY, or the logical type tag of a stored scalar followed by its order-preserving payload.

occurrence_value_hash

Canonical value hash of an occurrence (null and the empty-array marker share the null hash, as the planner assigns them).
