Struct VectorLite

pub struct VectorLite<const N: usize> { /* private fields */ }

A lightweight lsh-based ann index.

Implementations

impl<const N: usize> VectorLite<N>

pub fn new(num_trees: usize, max_leaf_size: usize) -> Self

Create a new VectorLite index with the given number of trees and max leaf size. More trees means more accuracy but slower search and larger memory usage. Lower max_leaf_size means higher accuracy but larger memory usage.

pub fn to_bytes(&self) -> Vec<u8>

pub fn from_bytes(bytes: &[u8]) -> Self
