Module lowering 

Read-only einsum lowering plans.

These wrappers expose shape and mode metadata computed by the ordinary einsum planner without exposing graph-building or arithmetic execution.

Examples

use tenferro_einsum::{ContractionTree, Subscripts};

let subs = Subscripts::new(&[&[0, 1], &[1, 2]], &[0, 2]);
let tree = ContractionTree::from_pairs(&subs, &[&[2, 3], &[3, 4]], &[(0, 1)]).unwrap();
let gemm = tree.step_plan(0).unwrap().gemm();

assert_eq!(gemm.contracted_modes(), &[1]);
