Sometimes aggressive auto-formatting (via apheleia or rustic) happens to be unwelcome for certain projects which prefer a more artisinal approach to semantics 1. Disabling this generally requires setting directory-local variables.

I found it necessary to inhibit apheleia and disable LSP formatting to prevent the editor from mangling the code on save.

1;; .dir-locals.el
2((rustic-mode . ((rustic-format-on-save . nil)
3                 (eval . (setq-local +format-with-lsp nil)))))
4((nil . ((eval . (progn
5                   (setq-local apheleia-inhibit t)
6                   (setq-local rustic-format-on-save nil)
7                   (setq-local +format-with-lsp nil))))))

Probably ought to be a nicer way, perhaps something in the doom local configuration.
