Struct CpuI8VectorActivation 

pub struct CpuI8VectorActivation<const N: usize>;

Parametric element-wise activation kernels over an N-element i8 vector.

N is the vector length. The same kernels (ReLU, Q1.7 sigmoid) are applied to every element independently; per-element determinism composes to per-vector determinism per ADR-030.

Trait Implementations

impl<const N: usize> ActivationAxis for CpuI8VectorActivation<N>

const AXIS_ADDRESS: &'static str = "https://uor.foundation/axis/ActivationAxis/CpuI8Vector"

const MAX_OUTPUT_BYTES: usize = N

Vector byte-width (overridden per impl).

fn relu(input: &[u8], out: &mut [u8]) -> Result<usize, ShapeViolation>

Apply ReLU elementwise.

fn sigmoid_q(input: &[u8], out: &mut [u8]) -> Result<usize, ShapeViolation>

Apply Q1.7 piecewise-linear sigmoid elementwise.

impl<const N: usize> AxisExtension for CpuI8VectorActivation<N>

const AXIS_ADDRESS: &'static str = <CpuI8VectorActivation<N> as ActivationAxis>::AXIS_ADDRESS

ADR-017 content address of this axis trait. The SDK macro derives this from the trait name and method signatures.

const MAX_OUTPUT_BYTES: usize = <CpuI8VectorActivation<N> as ActivationAxis>::MAX_OUTPUT_BYTES

Maximum bytes any kernel of this axis returns.

fn dispatch_kernel( kernel_id: u32, input: &[u8], out: &mut [u8], ) -> Result<usize, ShapeViolation>

Dispatch the kernel identified by kernel_id against the evaluated input bytes. The implementation copies the kernel’s output into out and returns the written length.

impl<const N: usize> Clone for CpuI8VectorActivation<N>

fn clone(&self) -> CpuI8VectorActivation<N>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<const N: usize> Debug for CpuI8VectorActivation<N>

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

Formats the value using the given formatter.

impl<const N: usize> Default for CpuI8VectorActivation<N>

fn default() -> CpuI8VectorActivation<N>

Returns the “default value” for a type.

impl<const N: usize> SubstrateTermBody for CpuI8VectorActivation<N>

fn body_arena() -> &'static [Term]

The Term arena the kernel decomposes to. Empty slice signals a primitive-fast-path axis whose body the implementation may evaluate through dispatch_kernel directly per ADR-055’s optional fast-path.
