Struct PQCodebook 

pub struct PQCodebook { /* private fields */ }

Euclidean chunk centroids. Resident ownership retains its allocation allowance, independently of query cancellation.

Implementations

impl PQCodebook

pub const CODEC_REVISION: u32 = 1

pub const TRAINING_REVISION: u32 = 1

pub fn dimensions(&self) -> usize

pub fn pq_bytes(&self) -> usize

pub fn centroid_count(&self) -> u16

pub fn training(&self) -> PQTrainingSummary

pub fn chunk_range(&self, chunk: usize) -> Option<Range<usize>>

pub fn chunk_centroids(&self, chunk: usize) -> Option<&[f64]>

Centroid-major coordinates for one contiguous chunk, using scalar f64 values.

pub fn encode( &self, vector: &NavigationVector, control: &StorageReadControl, ) -> StorageBackendResult<BudgetedVec<u8>>

pub fn lookup( &self, query: &NavigationVector, control: &StorageReadControl, ) -> StorageBackendResult<PQLookupTable>
