One more thing, if possible, I would like to limit of the watch file for just the files inside the device folder. That said, If you really had a concrete use case where the models module needed to be compilable without relying on the db module, then a relatively ugly solution would be to use cfg_attr like so: You would also have to set up the feature in Cargo.toml, and in a real use of this technique probably actually separate db and models into separate crates, and make the db crate only depended upon conditionally which I have not explained here.

Once these are in place, the entire module tree is built and looks like this: Each module can refer to any other module in the tree much like you can use the filesystem: absolute paths begin with crate (which is like /), and relative paths begin with self (.) I'm leaning towards defining separate structs between the domain-layer and it's implementation since it feels like the other option might still cause some bleeding between the layers. I'll give this a try and let you know. | unsafe?
