ＭＡＲＳ

A data science notebook for Rust.

• a full Rust context based off evxcr
• Can dynamically loading dependencies using evxcr :dep command (e.g. :dep random)
• single binary

Installation

Mars runs on a server on your machine. Running its binary will start the server and open up a browser to the tool.

cargo install mars
mars

Examples

Getting a random number

:dep rand
use rand::Rng;

let mut rng = rand::thread_rng();

let n1: u8 = rng.gen();
let n2: u16 = rng.gen();
println!("Random u8: {}", n1);
println!("Random u16: {}", n2);
println!("Random u32: {}", rng.gen::<u32>());
println!("Random i32: {}", rng.gen::<i32>());
println!("Random float: {}", rng.gen::<f64>());
