Struct PreparedQuery

Source

pub struct PreparedQuery { /* private fields */ }

Expand description

A query rotated into RaBitQ space, reusable across many candidate estimates.

Implementations§

Source §

impl PreparedQuery

Source

pub fn rq(&self) -> &[f32]

R·(q − c) — the rotated query residual, borrowed.

Exposed for callers that fold the estimator into their own SIMD kernel rather than going through RaBitQuantizer::estimate_dist_sq — that method takes &RaBitCode, which owns a Vec<u8>, so building one per candidate to call it would allocate on every distance computation in a hot graph-traversal loop.

Source

pub fn qn_sq(&self) -> f32

‖q − c‖².
