Struct QuantizedVector 

pub struct QuantizedVector {
    pub bits: Vec<u8>,
    pub dist_to_centroid: f32,
    pub self_dot: f32,
    pub popcount: u32,
}

Quantized representation of a single vector

Fields

bits: Vec<u8>

Binary quantization code (D bits packed into bytes)

dist_to_centroid: f32

Distance from original vector to centroid: ||o_raw - c||

self_dot: f32

Dot product of normalized vector with its quantized form: <o, o_bar>

popcount: u32

Number of 1-bits in the binary code (for fast computation)
