How to disable dead code warnings at the crate level in Rust?

Hi everyone! I'm new to Rust and working on my first small project. I have a library crate where I've defined several helper functions and structs. The problem is that many of them are not yet used in the main code — I've just started development and am writing functionality gradually. The Rust compiler constantly gives warnings like: `warning: function is never used: 'helper_func'`. For example: ```rust // lib.rs pub fn helper_func(x: i32) -> i32 { x * 2 } fn internal_helper(x: i32) -> i32 { x + 1 } pub struct Config { pub timeout: u32, pub retries: u32, } ``` `helper_func` and `internal_helper` are not called yet, and `Config` is not used. I have to suppress each warning with `#[allow(dead_code)]` above every function
