Struct Bits1Query 

pub struct Bits1Query {
    pub norm_sq: f32,
    /* private fields */
}

A query prepared for popcount scoring against 1-bit codes.

Fields

norm_sq: f32

Exact ‖q‖².

Implementations

impl Bits1Query

pub fn new(rotated: &[f32]) -> Result<Self, TurboQuantError>

Build from the rotated f32 query (same input the Turbo4 query prep uses; qscale/norm_sq semantics identical to encode_query).

pub fn distance_to(&self, metric: Metric, blob: &[u8]) -> f32

Estimated distance to a 1-bit code blob under metric. Pure AND+POPCNT per plane; conventions match the Turbo4 scorers.

pub fn to_blob(&self) -> Vec<u8>

Serialize into the flat query-blob form consumed by query_blob_distance — this is what travels through hnsw_rs::Distance<u8>::eval in cascade mode.

Layout: [8 planes × bits_len | 8 × plane_pop u32 | qscale | ‖q‖²].
