stage 0 rustfmt to format them.
The recommended `rust-analyzer` settings live at [`src/etc/rust_analyzer_settings.json`].

The default `rust-analyzer.check.overrideCommand` command line will check all the crates and tools
in the repository. If you are working on a specific part, you can override the command to only
check the part you are working on to save checking time. For example, if you are working on
the compiler, you can override the command to `x check compiler --json-output` to only
check the compiler part. You can run `x check --help --verbose` to see the available parts.

If you have enough free disk space and you would like to be able to run `x` commands while
rust-analyzer runs in the background, you can also add `--build-dir build-rust-analyzer` to the
`overrideCommand` to avoid x locking.
