Struct HnswIndex 

pub struct HnswIndex { /* private fields */ }

HNSW vector index backed by usearch.

Implementations

impl HnswIndex

pub fn new(config: VectorConfig) -> Result<Self, CodememError>

Create a new HNSW index with the given configuration.

pub fn with_defaults() -> Result<Self, CodememError>

Create a new index with default configuration (768-dim, cosine).

pub fn len(&self) -> usize

Get the number of vectors in the index.

pub fn is_empty(&self) -> bool

Check if the index is empty.

Trait Implementations

impl VectorBackend for HnswIndex

fn insert(&mut self, id: &str, embedding: &[f32]) -> Result<(), CodememError>

Insert a vector with associated ID.

fn insert_batch( &mut self, items: &[(String, Vec<f32>)], ) -> Result<(), CodememError>

Batch insert vectors.

fn search( &self, query: &[f32], k: usize, ) -> Result<Vec<(String, f32)>, CodememError>

Search for k nearest neighbors. Returns (id, distance) pairs.

fn remove(&mut self, id: &str) -> Result<bool, CodememError>

Remove a vector by ID.

fn save(&self, path: &Path) -> Result<(), CodememError>

Save the index to disk.

fn load(&mut self, path: &Path) -> Result<(), CodememError>

Load the index from disk.

fn stats(&self) -> VectorStats

Get index statistics.
