Rust Documentation - Testing Documentation Code Examples

//! ## 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
//! use documentation_test::meaning_of_life;
//! 
//! fn it_works() {
//!     assert_eq!(42, meaning_of_life(4));
//! }
//!
//! it_works();
//! ```

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));
    }
}
