Alternatively remove the `include` statement from `functions.jl`  
and only include `structs.jl` from main.

That depends a little bit on your desired program structure.  
Do you want doubly nested modules by making `structs` a submodule of `functions` which itself lives in `main`?

Alternatively both `functions` and `structs` could live in `main` directly.

Note however that all these modules are not necessary at all in your case here. In particular your `main` module does not seem to serve an purpose.
