Proof that it is still quite confusing, I tried to remove the mod.rs in my project similarly to that example but now I don't understand how to access these modules.

With the mod.rs in place I can do this in my main.rs:

  pub mod foo

and then in a different file do:

  use crate::foo::bar::*

But without the mod.rs it doesn't work and I don't know what the correct incantation is...

Edit:

Nevermind, I thought this update meant you could remove the mod.rs completely but this is about declaring foo.rs as a file outside of the foo folder.

So you can't just do this like I was hoping:

  .
  ├── lib.rs
  └── foo/
    └── bar.rs
