Rust Testing Structure

Simple repository exemplifying a rust library structure that allows unit tests separation from business logic.

This allows unit tests to be performed without having to needlessly expose private members of a module by using the child-to-parent rules of discoverability in Rust.

The separate sub-module solution used in the foo module isn't able to handle Cargo.toml [dev-dependencies]. An alternative way of separating the test files is by using #[path = "./bar_test.rs"], which works correctly with Rust's development dependencies expectations.
