Rust - Use module in a parent directory

I have a file structure looking somewhat like the following:

src/
--clients/
----queue_client/
------mod.rs
--data_evaluator/
----data_evaluator.rs

In data_evaluator, I want to use the queue_client module, but when I do mod queue_client in data_evaluator.rs- I get the following error - File not found for module queue_client. It only finds the module if I move it into the data_evaluator folder.

My question is, how do I correctly use modules that are outside of the consumer code's directory? Apologies if there is an easy way to do this, I did try searching for quite a while and couldn't find a way.

You seem to be a bit confused. In Rust, you build the module tree. You use mod to register a module as a submodule of your current module. You use use to use a module within your current module. This article may clear some things up: http://www.sheshbabu.com/posts/rust-module-system/

Aside from that, to use a module that's higher in the tree than your current module, you use crate to get to the root of your module tree. So in your case, crate::clients::queue_client.
