Struct Int8Index 

pub struct Int8Index { /* private fields */ }

Index of int8 vectors for batch operations

Implementations

impl Int8Index

pub fn new(dim: usize) -> Self

Create a new int8 index

pub fn with_capacity(dim: usize, capacity: usize) -> Self

Create with pre-allocated capacity

pub fn add(&mut self, vector: &Int8Vector)

Add a vector to the index

pub fn add_f32(&mut self, vector: &[f32])

Add a fp32 vector (will be quantized)

pub fn len(&self) -> usize

Get number of vectors

pub fn is_empty(&self) -> bool

Check if empty

pub fn memory_bytes(&self) -> usize

Get memory usage in bytes

pub fn get(&self, idx: usize) -> Option<Int8Vector>

Get a vector by index

pub fn get_data(&self, idx: usize) -> &[i8]

Get raw data slice for a vector

pub fn dot_product_f32(&self, idx: usize, query: &[f32]) -> f32

Compute dot product with fp32 query for a specific vector

pub fn rescore_candidates( &self, candidates: &[(usize, u32)], query: &[f32], ) -> Vec<(usize, f32)>

Rescore candidates from binary search using int8 dot product

Takes (index, hamming_distance) pairs and returns (index, rescored_distance).

Trait Implementations

impl Clone for Int8Index

fn clone(&self) -> Int8Index

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
