pub fn resolve_axis(axis: u8, rank: usize) -> Result<usize, ShapeExprError>Expand description
Resolve a non-negative axis (or LAST) against rank (§6.20-0003).
pub since Increment C slice 1 (T2): the recipe-interior axis_last
resolver (fuel_graph::runtime_fused::resolve_rel_attrs) reuses this as
the single LAST→rank−1 evaluator instead of growing a second one.
