Work around `rust-analyzer` false-positive type errors

rust-analyzer incorrectly reports two type errors in `debug.rs`:

> expected &dyn Display, found &i32
> expected &dyn Display, found &i32

This is due to a known bug in r-a: (https://github.com/rust-lang/rust-analyzer/issues/11847).

In these particular cases, changing `&0` to `&0i32` seems to be enough to avoid the bug.
