Struct BbqQuery 

Source 
pub struct BbqQuery {
    pub centered: Vec<f32>,
    pub signs: Vec<u8>,
    pub query_norm: f32,
    pub query_dot_quantized: f32,
}
Expand description

Prepared query for BBQ distance computation.

Fields§

§centered: Vec<f32>

Query vector after centroid subtraction (FP32, length = dim).

§signs: Vec<u8>

Sign-packed bits of centered (length = dim.div_ceil(8)).

§query_norm: f32

‖centered‖₂ — stored in header residual_norm of a synthetic query entry for reuse across candidates.

§query_dot_quantized: f32

⟨centered, sign(centered)⟩ / query_norm — quantization quality factor.
