Enum PrecisionLoweringPlan 

pub enum PrecisionLoweringPlan {
    DefaultF32,
    NativeF16 {
        max_abs_operand: f32,
    },
    PolynomialTranscendental {
        op: TranscendentalOp,
        argument_bound: f32,
        degree: u8,
    },
}

Concrete lower/emit plan selected from a foundation precision hint.

Variants

DefaultF32

Keep the default f32/device-transcendental lowering.

NativeF16

Emit this site through native f16 ALU and widen the result to f32.

Fields

max_abs_operand: f32

Maximum absolute source operand carried from the foundation hint.

PolynomialTranscendental

Emit a bounded polynomial for the transcendental instead of a native device call.

Fields

op: TranscendentalOp

Target operation.

argument_bound: f32

Maximum absolute argument bound from the foundation hint.

degree: u8

Required backend-side polynomial degree.

Trait Implementations

impl Clone for PrecisionLoweringPlan

fn clone(&self) -> PrecisionLoweringPlan

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for PrecisionLoweringPlan

impl Debug for PrecisionLoweringPlan

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

Formats the value using the given formatter.

impl PartialEq for PrecisionLoweringPlan

fn eq(&self, other: &PrecisionLoweringPlan) -> 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.
