Struct Scheme 

pub struct Scheme {
    pub block: Block,
    pub scale: Scale,
    pub words: u8,
}

A quantized activation’s scheme: its blocks, how each block’s scale is chosen, and the int8 words each value takes — one, the nearest whole number of the scale; two, a high word and a low word whose code is the nearest whole number of a finer step (the high word’s rest at a 128th of the scale, or a 16-bit code at a 256th); three, a third word at a 128th of the second’s step.

Fields

block: Block

scale: Scale

words: u8

Implementations

impl Scheme

pub const fn of(format: QuantFormat) -> Scheme

The scheme of an activation quantized in format: blocks of BLOCK under max / 127.

pub fn bound(&self) -> Bound

The bound a value read in this scheme keeps: half the finest step, where a scale max / 127 is that value or, a least power-of-two scale, up to 1 + 2^(1 − bits) times it, and an unsigned code’s half level under its scale at most max / 255; the slack terms cover the value and the scale read in f32 (a relative 2⁻²⁴ each, a sixteenth of a step of the block where that is less than 2⁻²⁰ of it), a denormal flushed to zero, and a scale’s floor.

Trait Implementations

impl Clone for Scheme

fn clone(&self) -> Scheme

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Scheme

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

Formats the value using the given formatter.

impl Hash for Scheme

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

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 Scheme

fn cmp(&self, other: &Scheme) -> 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 Scheme

fn eq(&self, other: &Scheme) -> 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 Scheme

fn partial_cmp(&self, other: &Scheme) -> 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.
