Struct PdxIndex 

pub struct PdxIndex { /* private fields */ }

A full vector set in PDX layout: a sequence of vertical blocks.

Implementations

impl PdxIndex

pub fn from_rows(vectors: &[&[f32]]) -> Self

Build from row-major vectors.

Panics

If vectors is empty, or any vector’s length differs from the first.

pub fn dim(&self) -> usize

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn block_count(&self) -> usize

pub fn euclidean_sq_into(&self, query: &[f32], out: &mut [f32])

Squared euclidean distance from query to every indexed vector.

This is the bulk API the row-major batch path lacks — the second lever in ADR-279 §5.1, worth 1.85–3.04× independently of layout, because it amortizes dispatch and lets the prefetcher see a sequential stream.

Panics

If out.len() < self.len().

pub fn dot_into(&self, query: &[f32], out: &mut [f32])

Dot product from query to every indexed vector.

pub fn euclidean_sq(&self, query: &[f32]) -> Vec<f32>

Convenience allocating wrapper.
