OccurrenceRow

Struct OccurrenceRow 

Source
pub struct OccurrenceRow {
    pub owner_kind: OwnerKind,
    pub owner_ord: u64,
    pub property_id: u64,
    pub family_id: u64,
    pub elem_ordinal: Option<u64>,
    pub occurrence_value: OccurrenceValue,
}
Expand description

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).

Fields§

§owner_kind: OwnerKind

Whether the owning row is a record or a relationship.

§owner_ord: u64

Dense ordinal of the owning row.

§property_id: u64

Property id this occurrence belongs to.

§family_id: u64

Property family this occurrence belongs to.

§elem_ordinal: Option<u64>

Element index within an array property, or None for scalars.

§occurrence_value: OccurrenceValue

The occurrence’s value state. The value hash is not carried: it is a function of this state and the canonical bytes (occurrence_value_hash).
