Is `mod.rs` the right name for the directory owning module?

@Letheed

many buffers named mod.rs when editing with in emacs, not very ergonomic…

I just want to say that M-x toggle-uniquify-buffer-names is your friend here.

@Letheed

need to rename the file when going from foo.rs to foo/mod.rs, you can't just move it

Oh and since I know you use emacs, M-x rust-promote-module-into-dir.

(This post is not meant to invalidate the broader point, since some people persist in not using emacs.)
