Crate strided_perm 

Cache-efficient tensor permutation / transpose.

This crate provides optimized copy and permutation operations for strided multidimensional arrays. It is designed as a single-responsibility crate sitting between strided-view (data structures) and strided-kernel (general map/reduce/broadcast operations).

Dependency graph

strided-view -> strided-perm -> strided-kernel -> strided-einsum2
