Struct QuantScheme

pub struct QuantScheme {
    pub value: QuantValue,
    pub param: QuantParam,
    pub store: QuantStore,
    pub level: QuantLevel,
    pub mode: QuantMode,
}

Describes a quantization scheme/configuration.

Fields

value: QuantValue

The logical data type of quantized input values (e.g., QInt8).

This defines how values are interpreted during computation, independent of how they’re stored.

param: QuantParam

Precision used for quantization parameters (e.g., scale and biases).

store: QuantStore

Data type used for storing quantized values.

level: QuantLevel

Granularity level of quantization (e.g., per-tensor).

mode: QuantMode

Quantization mode (e.g., symmetric).

Implementations

impl QuantScheme

pub fn with_level(self, level: QuantLevel) -> QuantScheme

Set the quantization level.

pub fn with_mode(self, mode: QuantMode) -> QuantScheme

Set the quantization mode.

pub fn with_value(self, value: QuantValue) -> QuantScheme

Set the data type used for quantized values.

pub fn with_store(self, store: QuantStore) -> QuantScheme

Set the data type used to store quantized values.

pub fn with_param(self, param: QuantParam) -> QuantScheme

Set the precision used for quantization parameters

pub fn size_bits_stored(&self) -> usize

Returns the size of the quantization storage type in bits.

pub fn size_bits_value(&self) -> usize

Returns the size of the quantization storage type in bits.

pub fn num_quants(&self) -> usize

Returns the number of quantized values stored in a single element.

pub fn native_packing(&self) -> usize

Returns the native packing factor for the values. When native packing > 1, the packed representation stores num_quants elements grouped into packs of native_packing size.

Trait Implementations

impl Clone for QuantScheme

fn clone(&self) -> QuantScheme

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for QuantScheme

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

Formats the value using the given formatter.

impl Default for QuantScheme

fn default() -> QuantScheme

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for QuantScheme

fn deserialize<__D>( __deserializer: __D, ) -> Result<QuantScheme, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for QuantScheme

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for QuantScheme

fn cmp(&self, other: &QuantScheme) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for QuantScheme

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

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

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for QuantScheme

fn partial_cmp(&self, other: &QuantScheme) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for QuantScheme

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
