Struct ThreeStageIndex 

Source 
pub struct ThreeStageIndex { /* private fields */ }
Expand description

Three-stage funnel: coarse_dim → mid_dim filter → full_dim rerank.

Distance ops breakdown:

  • Stage 1 traversal: O(ef × M) at coarse_dim dims
  • Stage 2 filter: O(coarse_candidates) at mid_dim dims
  • Stage 3 rerank: O(mid_candidates) at full_dim dims
