Struct Codec 

pub struct Codec { /* private fields */ }

Implementations

impl Codec

pub fn new(dim: usize, seed: u64) -> Codec

pub fn dim(&self) -> usize

pub fn n_byte_groups(&self) -> usize

pub fn encode_packed(&self, vector: &[f32]) -> (Vec<u8>, f32)

Encode vector into the packed 4-bit code groups + pre-rotation L2 norm without appending to any storage. This is the persistence-layer entry point used by TurboExtent::append in the durable write path (#693). The BlockedCodeStorage::append view of the same bytes is what the in-memory scorer reads.

pub fn encode_into( &self, storage: &mut BlockedCodeStorage, vector: &[f32], ) -> EncodedVector

Encode vector and append it to storage. Returns a handle the caller can pass back to Self::score_many (indirectly through the storage itself).

pub fn scalar_score( &self, query: &[f32], candidate: &[f32], metric: DistanceMetric, ) -> f32

pub fn score_many( &self, query: &[f32], storage: &BlockedCodeStorage, metric: DistanceMetric, ) -> Vec<f32>

Score query against every vector currently in storage. Returns a Vec<f32> of length storage.n_blocks() * BLOCK_LANES indexed by block_idx * BLOCK_LANES + lane; entries in unused trailing-block lanes are filled with f32::NEG_INFINITY.

Trait Implementations

impl Clone for Codec

fn clone(&self) -> Codec

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Codec

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.
