Rust Documentation - 2 weeks l;ater

//! ## Documentation Example
//! 
//! This is a lot of great documentation, you ought to read and maintain this. 
//! 
//! Somehow i think, you are going to not do that. 
//! 
//! ```rust
//! fn it_works() {
//!     assert_eq!(2 + 2, 4);
//! }
//! ```

pub fn meaning_of_life(multiplier: i64) -> i64 {
    return 42;
}

#[cfg(test)]
mod tests {
    use super::*;

    #[test]
    fn it_works() {
        assert_eq!(42, meaning_of_life(4));
    }
}
