Struct VectorIndex 

pub struct VectorIndex { /* private fields */ }

Wrapper around HNSW index

Implementations

impl VectorIndex

pub fn new(dimensions: usize, metric: DistanceMetric) -> VectorIndex

Create a new vector index

pub fn add( &mut self, node_id: NodeId, vector: &Vec<f32>, ) -> Result<(), VectorError>

Add a vector to the index

pub fn search( &self, query: &[f32], k: usize, ) -> Result<Vec<(NodeId, f32)>, VectorError>

Search for nearest neighbors

pub fn dimensions(&self) -> usize

Get dimensions

pub fn metric(&self) -> DistanceMetric

Get metric

pub fn len(&self) -> usize

Get count of stored vectors

pub fn is_empty(&self) -> bool

Check if index is empty

pub fn dump(&self, path: &Path) -> Result<(), VectorError>

Save index to disk by serializing stored vectors via bincode. On load, vectors are re-inserted into a fresh HNSW index.

pub fn load( path: &Path, dimensions: usize, metric: DistanceMetric, ) -> Result<VectorIndex, VectorError>

Load index from disk: deserialize stored vectors and re-insert into HNSW.

impl Debug for VectorIndex

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

Formats the value using the given formatter.
