| LL | fn mk_int() -> usize { let i: isize = 3; return i; } |
| | ----- ^ expected `usize`, found `isize` |
| | | |
| | expected `usize` because of return type |
| | |
| help: you can convert an `isize` to `usize` and panic if the converted value wouldn't fit |

| LL | fn mk_int() -> usize { let i: isize = 3; return i.try_into().unwrap(); } |
| | ^^^^^^^^^^^^^^^^^^^^^ |
