Rust code fails to get recognized as "used" by the compiler

[ninjaboy667]

Has anyone else run into this issue? My general strategy for my tauri app has been.

1. Create an .rs file for things i want to do
2. as to to main.rs and add it as pub to lib.rs
3. wrap those functions around essentially wrapper functions which have the tauri::command macro. and include them in my generate handler

I am getting a ton of warnings of unused code even though the program still runs fine with yarn tauri dev. Whats the recommended strategy? #[allow(dead_code)] everywhere?

with point 3) in place you shouldn't get dead code warnings about the functions you use there 🤔 do you perhaps have a direct example project for us to look at?

Here is an example, I have a bunch of global resources i am using for the life of the program:

here is a command from lib.rs that calls the global lifetime.
but it still thinks that "SCRIPT" is unused.

// Get connection status
#[tauri::command]
fn set_test_script(json: String) -> String {
// Step 1: Parse the JSON string into a ScriptObject
let script = match command::ScriptObject::from_json_string(&json) {
Ok(s) => s,
Err(e) => return format!("Failed to parse script: {}", e),
};

// Step 2: Lock the global DYNO and insert the script
match SCRIPT.lock() {
    Ok(mut guard) => {
        *guard = Some(script);
        "Script object set in rust successfully".to_string()
    }
    Err(poisoned) => {
        let mut guard = poisoned.into_inner();
        *guard = Some(script);
        "Script object set (recovered from poisoned lock)".to_string()
    }
}

}

the code works, ive already tested it.

As I just found out, cargo will compile the app twice, once for lib.rs and once for main.rs. And if there are warnings in either it will show them to you. The IDE doesn't know the difference, and just shows you warnings the compiler generated

The solution for this is to remove mod module_name declarations from main.rs. If you need those modules, import them from the appname_lib namespace
