Rust general-purpose programming language that emphasizes performance. It is a lower-level general-purpose programming language featuring memory safety, thread safety, cross-platform support, and zero-cost abstractions.

/* genrates a number 1-20 10 times */
use rand::distributions::{Distribution, Uniform};

fn main() {
let roll = 10;
let dice = 20;
    let mut rng = rand::thread_rng();
    let die = Uniform::from(1..dice+1);
    let mut i = 0;

    while i < roll {
        let throw = die.sample(&mut rng);
        println!("die: {}", throw);
        i = i + 1;
    }
}

To Install: #

Preferred method

The easiest way to Install Rust and Cargo is to install the current stable release of Rust using rustup. Installing Rust using rustup will also install cargo.

sudo pacman -S rustup

sudo apt install rustup

sudo dnf install rustup

sudo zypper in rustup

Additional install options

The official way of installing rustup on Linux is

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

It will download a script, and start the installation. If everything goes well, you’ll see this appear:

Rust is installed now. Great!
