Struct Dot 

pub struct Dot;

Dot-product pairwise operation: multiply two vectors lane-wise.

Use with zip_reduce: a.zip_reduce(&b, Dot) equals a.dot(&b).

Trait Implementations

impl Clone for Dot

fn clone(&self) -> Dot

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Dot

impl Debug for Dot

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

Formats the value using the given formatter.

impl Eq for Dot

impl PartialEq for Dot

fn eq(&self, other: &Dot) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl<T> ReductionOp<T> for Dot

where T: NumericElement,

unsafe fn accumulate<Arch>( acc: <Arch as SimdKernel<T>>::Vector, v: <Arch as SimdKernel<T>>::Vector, ) -> <Arch as SimdKernel<T>>::Vector

where Arch: SimdKernel<T>,

Dot accumulation: acc = fmadd(a, b, acc) — called with the pairwise product vector.

The zip_reduce loop computes v = mul(a_chunk, b_chunk) then calls accumulate(acc, v).

unsafe fn fma_pair_accumulate<Arch>( acc: <Arch as SimdKernel<T>>::Vector, a: <Arch as SimdKernel<T>>::Vector, b: <Arch as SimdKernel<T>>::Vector, ) -> <Arch as SimdKernel<T>>::Vector

where Arch: SimdKernel<T>,

FMA-accelerated pairwise accumulation for dot product.

Overrides the default accumulate(acc, mul(a, b)) two-instruction sequence with a single fmadd(a, b, acc) when the architecture supports it.

unsafe fn finalize<Arch>(acc: <Arch as SimdKernel<T>>::Vector) -> T

where Arch: SimdKernel<T>,

Reduce the final accumulator to a scalar.

fn identity_scalar() -> T

The identity element for this reduction as a scalar.

fn scalar_combine(a: T, b: T) -> T

Combine two scalar partial results using this reduction.

fn scalar_accumulate(acc: T, elem: T) -> T

Accumulate a single scalar element elem into a scalar accumulator acc.

unsafe fn identity_vector<Arch>() -> <Arch as SimdKernel<T>>::Vector

where Arch: SimdKernel<T>,

Splat the identity element into a vector register.

unsafe fn transform_vector<Arch>( v: <Arch as SimdKernel<T>>::Vector, ) -> <Arch as SimdKernel<T>>::Vector

where Arch: SimdKernel<T>,

Per-element lane transform applied before combining (identity by default).

unsafe fn combine_vectors<Arch>( a: <Arch as SimdKernel<T>>::Vector, b: <Arch as SimdKernel<T>>::Vector, ) -> <Arch as SimdKernel<T>>::Vector

where Arch: SimdKernel<T>,

Merge two partial accumulators WITHOUT the per-element transform.
