FdeEncoder

uni_common::muvera

Struct FdeEncoder 

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

A reusable FDE encoder holding all repetitions’ random matrices. Build it ONCE per flush batch / per query (matrix generation is the expensive part) and reuse it across many encode_doc/encode_query calls.

Implementations§

Source§

impl FdeEncoder

Source

pub fn new(params: &FdeParams) -> Result<Self, FdeError>

Materialise all random matrices from the seed. Validates params.

Source

pub fn params(&self) -> &FdeParams

The parameters this encoder was built from.

Source

pub fn fde_dim(&self) -> usize

Output FDE dimension (== self.params().fde_dim()).

Source

pub fn encode_doc(&self, tokens: &[Vec<f32>]) -> Result<Vec<f32>, FdeError>

Encode a document multi-vector: per-bucket centroid + empty-bucket fill.

Source

pub fn encode_query(&self, tokens: &[Vec<f32>]) -> Result<Vec<f32>, FdeError>

Encode a query multi-vector: per-bucket sum, no centroid, no fill_empty.
