Install

Add to your cargo.toml file toml [dependencies] fateful = "0.1.1"

Usage

```rust use std::env; use rand; use fateful::{fatal, err_prefix};

fn main() { let args: Vec = env::args().collect(); if args.len() < 3 { fatal!(err_prefix!(), "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!("U need to study: {} 🎉", random_items[index]);

} If u don't provide at least 2 arguments after `cargo run` the output will be: Error: missing random items to choose of ```
