Struct PhysicalAxisMap 

pub struct PhysicalAxisMap { /* private fields */ }

One buffer dim as (Σ coordinate(axis) * scale + offset) / divisor, floored.

Implementations

impl PhysicalAxisMap

pub fn broadcast() -> Self

A map addressing no logical axis: every position resolves to the same element.

pub fn of(axis: Axis) -> Self

pub fn disjoint(terms: &[(Axis, usize)]) -> Self

This physical axis partitioned by several logical ones, coarsest first: disjoint(&[(KB, 32), (KI, 1)]) is k = kb * 32 + ki.

pub fn affine(terms: &[(Axis, usize)]) -> Self

An affine combination, e.g. affine(&[(Oh, stride), (Rh, dilation)]).

pub fn scaled(terms: &[(Axis, Scale)]) -> Self

affine over explicit Scales, for runtime coefficients.

pub fn shifted(self, offset: impl Into<Offset>) -> Self

The same combination plus a signed constant or dynamic offset, added before any over.

pub fn over(self, divisor: impl Into<Divisor>) -> Self

The same combination divided by divisor, floored; a divisor every coefficient cancels is reduced away.

pub fn offset(&self) -> Offset

The offset of this physical axis.

pub fn scale(&self, axis: Axis) -> usize

axis’s coefficient, 0 when it does not address this axis. Panics if it is dynamic.
