    pub scale: f32,
    pub zero_point: i32,
    pub qtype: QuantizationType,
    pub range: (f32, f32),
}

Quantization parameters (scale and zero-point)

Fields

Scaling factor

zero_point: i32

Zero point (offset)

qtype: QuantizationType

Quantization type

range: (f32, f32)

Value range (min, max) from calibration

Implementations

impl QuantizationParams

pub fn new(scale: f32, zero_point: i32, qtype: QuantizationType) -> Self

Create new quantization parameters

Arguments

• scale - Scaling factor
• zero_point - Zero point offset
• qtype - Quantization type

pub fn from_range( min_val: f32, max_val: f32, qtype: QuantizationType, scheme: QuantizationScheme, ) -> Self

Compute quantization parameters from value range

Arguments

• min_val - Minimum value in the data
• max_val - Maximum value in the data
• qtype - Quantization type
• scheme - Quantization scheme (symmetric/asymmetric)

pub fn quantize(&self, value: f32) -> i32

Quantize a floating-point value

pub fn dequantize(&self, quantized: i32) -> f32

Dequantize an integer value back to floating-point

pub fn quantize_array(&self, values: &[f32]) -> Vec<i32>

Quantize an array of values

pub fn dequantize_array(&self, quantized: &[i32]) -> Vec<f32>

Dequantize an array of values
