Struct LshIndex 

pub struct LshIndex { /* private fields */ }

LSH index implementation

Implementations

impl LshIndex

pub fn new(config: LshConfig) -> Self

Create a new LSH index

pub fn stats(&self) -> LshStats

Get statistics about the index

Trait Implementations

impl VectorIndex for LshIndex

fn insert(&mut self, uri: String, vector: Vector) -> Result<()>

Insert a vector with associated URI

fn search_knn(&self, query: &Vector, k: usize) -> Result<Vec<(String, f32)>>

Find the k nearest neighbors, returned as (id, similarity) sorted by descending similarity (best match first). See the trait-level score contract: the score is a similarity, not a distance.

fn search_threshold( &self, query: &Vector, threshold: f32, ) -> Result<Vec<(String, f32)>>

Find all vectors whose similarity to query is >= threshold.

fn get_vector(&self, uri: &str) -> Option<&Vector>

Get a vector by its URI

fn add_vector( &mut self, id: VectorId, vector: Vector, _metadata: Option<HashMap<String, String>>, ) -> Result<()>

Add a vector with associated ID and metadata

fn update_vector(&mut self, id: VectorId, vector: Vector) -> Result<()>

Update an existing vector

fn update_metadata( &mut self, _id: VectorId, _metadata: HashMap<String, String>, ) -> Result<()>

Update metadata for a vector

fn remove_vector(&mut self, _id: VectorId) -> Result<()>

Remove a vector by its ID

fn iter_vectors(&self) -> Vec<(String, Vector)>

Iterate all stored (id, vector) pairs.

fn supports_enumeration(&self) -> bool

Whether VectorIndex::iter_vectors returns a real, complete enumeration of the vectors held by this index.
