Struct PdxBlock 

pub struct PdxBlock { /* private fields */ }

A block of up to LANES vectors stored dimension-major.

Implementations

impl PdxBlock

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

Transpose up to LANES row-major vectors into one vertical block.

Panics

If vectors is longer than LANES, or any vector’s length differs from dim. Both are programming errors rather than input errors — a ragged block would silently produce wrong distances.

pub fn dim(&self) -> usize

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

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

Squared euclidean distance from query to every vector in the block.

Writes self.len() results. Padding lanes are computed but discarded — branchless, and they hold zeros so they cannot fault or produce NaN.

Panics

If query.len() != self.dim() or out.len() < self.len().

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

Dot product from query to every vector in the block.
