Rust macros

Readme.md

List of useful macros

log!

This macro just logs values (think console.log in js).

Example usage: log!(1,2,3,"hello world", [1,2,3])

min!

This macro returns minimum value of provided i32's (think Math.min in js).

Two implementations, one using vec is O(n) the other is O(1) space

Example usage: min!(1,2,3,4,-123) will return -123

macro_rules! log {
    ($($arg:tt)*) => {
        println!("{:?}", ($($arg)*));
    }
}

#[macro_export]
macro_rules! min {
    ($($arg:tt)*) => {
        vec![$($arg)*].iter().min().unwrap();
    }
}

#[macro_export]

    ($($arg:expr),*) => {
        {
            let mut min_val = i32::MAX;

            $(
                if($arg < min_val) {
                    min_val = $arg;
                }
            )*

            min_val
        }
    };
}

#[macro_export]
macro_rules! max {
    ($($arg:expr),*) => {
        {
            let mut max_val = i32::MIN;

            $(
                if($arg > max_val) {
                    max_val = $arg;
                }
            )*

            max_val
        }
    };
