I have a Rust project split into 3 files:

• main.rs
• config.rs
• generate.rs

Inside config.rs are variables which are given values by TOML structs. I am required to inject those variables into generate.rs as part of a function within that module. I have imported the config module, yet the compiler throws errors regarding the variables being out-of-scope. The variables are within a function in config.rs as Rust seems to disallow using let in global scope.

How can I allow Rust to inject immutable let variables from another module into a module's function?
