Crate fateful

A tool to fatefully exit the process without panics

(Pseudo-)Example:

use std::env;
use rand;
use fateful::fatal;

fn main() {
    let args: Vec<String> = env::args().collect();
    if args.len() < 3 {
        fatal!("missing random items to choose of");
    }

    let random_items: &Vec<String> = &args[1..args.len()].to_vec();
    let index = (rand::random::<f32>() * random_items.len() as f32).floor() as usize;
    println!("Random: {} 🎉", random_items[index]);
}
