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

Hi! I've just started learning Rust and encountered an annoying problem. I have a crate with many helper functions written for future features. For example, I'm implementing a library for working with matrices, and it has functions that are not used yet but will be needed in the next sprint: ```rust // This is part of my matrix_ops library pub fn transpose(matrix: &Vec>) -> Vec> { // implementation... } pub fn determinant(matrix: &Vec>) -> i32 { // implementation... } fn main() { let m = vec![vec![1, 2], vec![3, 4]]; // currently only using transpose let t = transpose(&m); println!("{:?}", t); } ``` When compiling, I get a bunch of warnings like: ``` warning: function `determinant` is never used --> sr ```
