From JS to Rust

Rocket turtles to crustaceans

Probably even more important than its features is the ecosystem and the community behind the language. Rust really shines here - especially for people who love the web.

How?

use std::io;

fn main() {
    println!("Please input the temperature in Celsius.");

    let mut temperature = String::new();
    io::stdin().read_line(&mut temperature)
            .expect("Failed to read line");


    let temperature: f32 = temperature.trim().parse()
        .expect("Please type a number!");

    println!("{}", (temperature * 9.0) / 5.0 + 32.0);
}

The package

• rustc - the compiler
• rust-std - the standard library
• cargo - package manager & commander
• rust-docs - documentation generator
