}

Precision levels for inference

Variants

INT4

4-bit integer (most aggressive compression)

INT8

8-bit integer

BF16

16-bit floating point (brain float)

FP16

16-bit floating point

FP32

32-bit floating point (full precision)

Implementations

impl Precision

pub fn bits(&self) -> u32

Bits per element

pub fn bytes(&self) -> f32

Bytes per element

pub fn vram_ratio(&self) -> f32

VRAM usage relative to FP32 (0.0 - 1.0)

pub fn speedup_factor(&self) -> f32

Approximate speedup factor relative to FP32

pub fn quality_factor(&self) -> f32

Quality impact (lower is more lossy) This is an approximation - actual impact depends on model and content

pub fn is_lossless(&self) -> bool

Whether this precision is lossless (or nearly so)

pub fn parse(s: &str) -> Option<Self>

Parse from string (returns None on failure)

Trait Implementations

impl Clone for Precision

fn clone(&self) -> Precision

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Precision

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

Formats the value using the given formatter.

impl Default for Precision

fn default() -> Precision

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Precision

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Precision

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

Formats the value using the given formatter.

impl FromStr for Precision

type Err = ()

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for Precision

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 Precision

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

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

fn partial_cmp(&self, other: &Precision) -> 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 Precision

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Precision

impl Eq for Precision

impl StructuralPartialEq for Precision
