Struct QuantizedU8 

#[repr(transparent)]
pub struct QuantizedU8(pub u8);

Quantized 8-bit unsigned integer.

This type is a 1-byte wrapper to match Numina’s canonical QU8 byte layout. Quantization parameters (scale/zero-point) are treated as external metadata.

Tuple Fields

0: u8

Implementations

impl QuantizedU8

pub fn from_raw(value: u8) -> Self

Wrap a raw quantized u8 storage value.

pub fn raw(self) -> u8

Return the underlying raw u8 storage value.

pub fn quantize(value: f32, scale: f32) -> Self

Quantize a f32 value using scale (no zero-point).

Values are rounded to the nearest integer and clamped to [0, 255].

pub fn dequantize(self, scale: f32) -> f32

Dequantize this value using scale (no zero-point).

Trait Implementations

impl Debug for QuantizedU8

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for QuantizedU8

fn default() -> QuantizedU8

Returns the “default value” for a type.

impl Display for QuantizedU8

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<QuantizedU8> for DType

fn from(_: QuantizedU8) -> Self

impl PartialEq for QuantizedU8

fn eq(&self, other: &QuantizedU8) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool
