Struct Rotate 

pub struct Rotate<const N: usize>;

Rotation: cyclically shifts the active slot.

On each clock cycle, the pipeline advances data for the next computation. After N cycles, all computations have advanced by one pipeline stage.

The rotation is a natural transformation ([A; N] -> [A; N] for all A: Copy). It commutes with any per-element operation, so applying a pipeline stage then rotating is the same as rotating then applying.

Note: this is not implemented via comp_cat_rs::foundation::nat_trans::NatTrans because that trait’s transform<A> has no bounds on A, and we require Copy (moving individual array elements without Copy is not possible in safe Rust without allocation). The naturality property holds for all A: Copy, which covers all hardware signal types.

Implementations

impl<const N: usize> Rotate<N>

pub fn apply<A: Copy>(arr: [A; N]) -> [A; N]

Rotate the array left by one position.

[a, b, c, d] becomes [b, c, d, a].
