Rust is a popular, open-source high-level programming language that was developed in 2006. It is designed for high performance and reliability while emphasizing on the code’s safety. Rust's syntax is similar to that of C++ and it is used to build a wide range of applications such as operating systems, game engines, browser components, and much more

Among the big tech giants that use Rust in their applications include Dropbox, Firefox, and Cloudflare. 

Here at Ibmi Media, as part of our Server Management Services, we regularly help our Customers to perform related Linux system Software Installation queries.

In this context, we shall look into how to install Rust programming language on Ubuntu 20.04.

Steps to install Rust programming language on Ubuntu

1. Perform system update

First, start by updating the system packages by running the command:

$ sudo apt update && sudo apt upgrade -y

2. Download and Install Rust

$ source ~/.profile
$ source ~/.cargo/env

How to test Rust Installation ?

We will run a simple hello world script to make sure rust is properly installed and configured on our machine:

$ mkdir ~/projects
$ cd projects

From the above command, First, we created a new folder to store the rust sample file.

Now, create the file:

$ sudo nano hello.rs

Then, append the following lines to the file:

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

Save the file. Thereafter, compile the rust file with the command:

$ rustc hello.rs

After that, an executable file will be created.

Now run the file to view the output of your program:

$ ./hello

The output 'Hello World' will be displayed.
