Struct IvfTqIndex 

pub struct IvfTqIndex {
    pub dim: usize,
    pub routing: IvfRoutingMode,
    pub centroids_version: u64,
    /* private fields */
}

IVF-TQ build payload for a single segment.

Fields

dim: usize

routing: IvfRoutingMode

centroids_version: u64

Version of coarse centroids used (for merge compatibility).

Implementations

impl IvfTqIndex

pub fn new( dim: usize, routing: IvfRoutingMode, centroids_version: u64, codec: Arc<TqCodec>, ) -> Self

pub fn codec(&self) -> &TqCodec

pub fn add_vector( &mut self, coarse_centroids: &CoarseCentroids, doc_id: u32, ordinal: u16, vector: &[f32], scratch: &mut TqIvfEncodeScratch, )

Add a single vector: assign to the trained router (with SOAR when configured) and TQ-encode the residual against every assigned leaf.

pub fn add_vectors_parallel( &mut self, coarse_centroids: &CoarseCentroids, doc_id_ordinals: &[(u32, u16)], vectors: &[f32], ) -> Result<(), &'static str>

Add one contiguous vector batch in parallel while preserving input order inside every leaf.

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn estimated_memory_bytes(&self) -> usize
