Enum FP8Format 

pub enum FP8Format {
    E4M3,
    E5M2,
}

FP8 data format specification

Variants

E4M3

E4M3: 4-bit exponent, 3-bit mantissa (sign: 1, exp: 4, mantissa: 3) Range: ±448, better dynamic range Best for: Forward pass, activations, weights

E5M2

E5M2: 5-bit exponent, 2-bit mantissa (sign: 1, exp: 5, mantissa: 2) Range: ±57344, wider range but less precision Best for: Gradients, loss scaling

Trait Implementations

impl Clone for FP8Format

fn clone(&self) -> FP8Format

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FP8Format

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FP8Format

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for FP8Format

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 PartialEq for FP8Format

fn eq(&self, other: &FP8Format) -> 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 Serialize for FP8Format

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 FP8Format
