Enum IndexKind 

pub enum IndexKind {
    Ordered,
    Text {
        consistency: TextConsistency,
    },
    Structural {
        dimensions: u32,
    },
}

What an index answers.

Variants

Ordered

Ordered entries (value, owner): equality, $in, ranges, prefix.

Text

Full-text (BM25) over the property’s string values — every string property of the record when the property is TEXT_ALL_PROPERTIES. Maintained by the text applier from pending rows.

Fields

consistency: TextConsistency

When a search sees a write.

Structural

Structural embeddings: one vector per record of the label, derived from the graph around it (FastRP over every relationship, ignoring direction), bound into the vector space named after the index. Maintained by the structural applier from pending rows: a relationship or record change marks the records within two hops. Its property is TEXT_ALL_PROPERTIES: it reads topology, not a property.

Fields

dimensions: u32

Vector dimensions.

Implementations

impl IndexKind

pub fn applied(self) -> bool

Whether an applier outside the store maintains the index from pending rows (text and structural), rather than apply-time entries.
