Struct Codebook 

pub struct Codebook {
    pub bits: u8,
    pub centroids: &'static [f32],
    pub boundaries: &'static [f32],
}

A scalar quantizer codebook for a given bit-width.

Fields

bits: u8

Bit-width (1-4).

centroids: &'static [f32]

Reconstruction centroids in ascending order (2^b values).

boundaries: &'static [f32]

Decision boundaries (2^b - 1 midpoints between consecutive centroids).

Implementations

pub fn quantize_scalar(&self, x: f32) -> u8

Find the index of the nearest centroid for a scalar value.

pub fn dequantize_scalar(&self, idx: u8) -> f32

Look up the centroid for a given index.
