Struct FlatIndex 

pub struct FlatIndex { /* private fields */ }

Flat vector index: append-only buffer with brute-force search.

Implementations

impl FlatIndex

pub fn new(dim: usize, metric: DistanceMetric) -> Self

Create a new empty flat index.

pub fn insert(&mut self, vector: Vec<f32>) -> u32

Insert a vector. Returns the assigned vector ID.

pub fn delete(&mut self, id: u32) -> bool

Soft-delete a vector by ID.

pub fn search(&self, query: &[f32], top_k: usize) -> Vec<SearchResult>

Brute-force k-NN search. Exact results — no approximation.

pub fn search_filtered( &self, query: &[f32], top_k: usize, bitmap: &[u8], ) -> Vec<SearchResult>

Search with a pre-filter bitmap (byte-array format).

pub fn len(&self) -> usize

pub fn live_count(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn get_vector(&self, id: u32) -> Option<&[f32]>

pub fn dim(&self) -> usize

pub fn metric(&self) -> DistanceMetric

pub fn tombstone_count(&self) -> usize
