Struct BinaryParams 

pub struct BinaryParams {
    pub thresholds: Vec<f32>,
    pub dimensions: usize,
}

Binary quantization parameters

Fields

thresholds: Vec<f32>

Threshold per dimension (typically 0.0 or median)

dimensions: usize

Number of dimensions

Implementations

impl BinaryParams

pub fn new(dimensions: usize) -> Self

Create with zero thresholds (value > 0 = 1, value <= 0 = 0)

pub fn train(vectors: &[&[f32]]) -> Result<Self, &'static str>

Train thresholds from sample vectors using median per dimension.

Errors

Returns error if vectors is empty or vectors have inconsistent dimensions.

pub fn quantize(&self, vector: &[f32]) -> Vec<u8>

Quantize f32 vector to packed binary

pub fn quantize_into(&self, vector: &[f32], output: &mut [u8])

Quantize into pre-allocated buffer
