Variants

BruteForceKnn

Exact neighbor search over the evaluated dataset.

IvfFlat

Approximate neighbor search with inverted lists storing full vectors.

IvfPq

Approximate neighbor search with product-quantized inverted lists.

Cagra

Approximate neighbor search with a query-local graph index.

PairwiseDistance

Evaluates every pair across two dense relations.

TopK

Selects the smallest or largest values within each dense row.

KMeans

Fits clusters and assigns the input rows.

Pca

Fits principal components and transforms the input rows.

Implementations

impl CuvsOperation

pub fn all() -> impl ExactSizeIterator + Clone

Iterates supported operations in the canonical registry order.

pub fn descriptor(self) -> &'static CuvsOperationDescriptor

Returns this operation’s static options, element support, and output contract.

pub fn from_sql_function_name(name: &str) -> Option<CuvsOperation>

Looks up an exact canonical SQL name; returns None for an unknown name.

This lookup does not normalize case.

Trait Implementations
