Struct Int8Codec 

pub struct Int8Codec { /* private fields */ }

Per-vector min/scale uniform int8: [min f32 | scale f32 | D bytes]. Same scheme as the legacy ScalarQuantized, but blob-oriented so the plane can move it around like any other representation.

Trait Implementations

impl VectorCodec for Int8Codec

fn kind(&self) -> CodecKind

Which representation this codec produces.

fn dim(&self) -> usize

Dimensionality of vectors this codec accepts.

fn encoded_len(&self) -> usize

Bytes per encoded vector.

fn encode(&self, v: &[f32]) -> Result<Vec<u8>>

Encode a vector. The blob is self-sufficient for scoring.

fn decode(&self, blob: &[u8]) -> Result<Vec<f32>>

Reconstruct an approximation (exact only for Fp32).

fn distance(&self, a: &[u8], b: &[u8]) -> Result<f32>

Symmetric blob×blob distance under this codec’s metric.

fn make_query(&self, q: &[f32]) -> Result<Box<dyn EncodedQuery>>

Prepare a query for repeated asymmetric scoring against blobs.
