Source

pub struct RoutingLayer { /* private fields */ }

Expand description

Compressed routing layer for cache-resident operations

Implementations§

Source §

impl RoutingLayer

Source

pub fn build(centroids: &[f32], dim: usize, config: RoutingConfig) -> Self

Build routing layer from FP32 centroids

Source

pub fn route(&self, query: &[f32], n_probes: usize) -> Vec<ListCandidate>

Route query to top-k lists

Two-stage process:

Coarse ranking using compressed centroids (cache-resident)
Refine top candidates using full precision (optional)

Source

pub fn update_cap(&mut self, list_idx: usize, cap: SphericalCapMetadata)

Update spherical cap metadata for a list

Source

pub fn memory_bytes(&self) -> usize

Get memory footprint

Source

pub fn fits_in_cache(&self) -> bool

Check if routing layer fits in target cache

Source

pub fn stats(&self) -> RoutingStats

Get routing statistics
