Rust

Rust is a systems programming language that emphasizes performance, reliability, and productivity. It provides memory safety without garbage collection and supports concurrent programming without data races. Rust is particularly well-suited for developing system tools, embedded systems, and performance-critical applications.

Install rust using rustup

Rustup is the official installer and version management tool for Rust. To install rustup run the below command.

# Download and run the rustup installer script
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

# Load Rust environment variables into current shell session
. "$HOME/.cargo/env"

After installation, verify that Rust is properly installed

$ rustc --version
$ cargo --version

Running an example

Let's create a simple Hello World program to test the installation:

1

Create a new directory, and a new source file for your rust program.

$ mkdir hello_rust && cd hello_rust
$ nano main.rs

2

Paste the following program in the editor

fn main() {
    println!("Hello, Rust!");
}

3

Now lets compile and run the program.

$ rustc main.rs
$ ./main 
Hello, Rust!

You are now ready to run our favorite crustacean compiler 🦀!
