Enum SchemaVectorIndexKind 

pub enum SchemaVectorIndexKind {
    Flat,
    HnswSquaredEuclidean,
    HnswCosine,

    IvfCosine,

}

Schema-level vector index algorithm kind.

This mirrors storage-level vector index algorithm selection without making selene-core depend on graph storage internals.

Variants

Flat

Exact in-memory row-set accelerator. ANN algorithms can be added as new variants without changing the (label, property) catalog identity.

HnswSquaredEuclidean

Approximate HNSW index using squared Euclidean distance.

HnswCosine

Approximate HNSW index using cosine distance.

HnswNegativeInnerProduct

Approximate HNSW index using negative inner product distance.

IvfSquaredEuclidean

Approximate IVF index using squared Euclidean distance.

IvfCosine

Approximate IVF index using cosine distance.

IvfNegativeInnerProduct

Approximate IVF index using negative inner product distance.

TurboQuantCosine

Compressed TurboQuant candidate index using cosine distance.

Trait Implementations

impl Clone for SchemaVectorIndexKind

fn clone(&self) -> SchemaVectorIndexKind

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for SchemaVectorIndexKind

impl Debug for SchemaVectorIndexKind

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SchemaVectorIndexKind

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for SchemaVectorIndexKind

impl PartialEq for SchemaVectorIndexKind

fn eq(&self, other: &SchemaVectorIndexKind) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for SchemaVectorIndexKind

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
