Why the non idiomatic rust file locations?

[joshka]

Hey, I saw that there's a bunch of places where you've chosen to avoid the rust idiomatic source arrangements and put the source files directly in the same folder as Cargo.toml. I wonder if you could explain the rationale for this. If I had to guess it's to make this attractive and familiar to existing C posix devs. I wonder if it might be worth catering to rust devs there?

Perhaps to make bins clearly stand out using the src/bins/foo.rs convention would be worth thinking about?
