| | ^ cannot perform const operation using `N` |

| = help: const parameters may only be used as standalone arguments here, i.e. `N` |
| = help: add `#![feature(generic_const_exprs)]` to allow generic const expressions |
| = help: alternatively, you can use `#![feature(generic_const_args)]` and extract the expression into a `type const` item |
