Enum Precision 

pub enum Precision {
    F32,
    F16,
    BF16,
}

Numeric precision for graph compilation.

Variants

F32

Full single precision. Always supported; accurate; baseline.

F16

Half precision (IEEE 754 binary16). Native on Apple Silicon GPU and many CPUs (NEON vfmaq_f16). 2× FLOPs / 0.5× memory vs F32. Reductions are still computed in F32 for numerical stability.

BF16

Brain-float: 8-bit exponent, 7-bit mantissa. Same range as F32, less precision. Used in many LLMs. Accelerator-dependent.

Implementations

impl Precision

pub fn size_bytes(self) -> usize

Bytes per scalar at this precision.

pub fn bytes(self) -> usize

Backward-compatible alias used in older code.

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 Display for Precision

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

Formats the value using the given formatter.

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 Copy for Precision

impl Eq for Precision

impl StructuralPartialEq for Precision
