[Solved] Rust import error

In your comments, you state:

I don’t want to use [mod functions] because it will search for settings/functions.rs, and it is not i want to

Have you tried that? Assuming you’ve declared the module correctly … this is exactly what you want.

main.rs:

mod functions;
mod settings;

fn main() { 
    ...
}

settings.rs:

use functions;

pub fn something() {
    functions::some_function_here();
}

If this does not work .. then there is something missing from your problem description.
