How to Install Rust on Manjaro 21 Linux

Rust is an open-source systems programming language that focuses on speed, memory safety, and parallelism. Developers use Rust to create a wide range of new software applications, such as game engines, operating systems, file systems, browser components, and simulation engines for virtual reality. Rust is syntactically similar to C++ but can guarantee memory safety by using a borrow checker for validating references.

In the following tutorial, you will learn how to install Rust Programming Language on Manjaro 21 Linux. The tutorial will use the command line terminal and install the official repository, which will lead you to have the most up-to-date version at times.

Update Manjaro

Before proceeding with the tutorial, it is good to ensure your system is up-to-date with all existing packages.

sudo pacman -Syu

Install Dependencies

Before proceeding further, run the following command to install the required packages needed to install and successfully run Rust on your system. The packages are well known and highly used amongst many similar types of installations.

sudo pacman -Sy curl

If you are unsure, just run the command regardless; it will do no harm.

Install Rust

Once you have completed the required installation of packages in prerequisites, you now can use (curl) to download the Rust installation script by executing the following command:

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

Next, you should see an output like the example below with a prompt about installing default or customizing the installation.

For most users, install the default Type 1 and press the ENTER KEY to continue unless you want to customize it.

Example:

The entire installation should take between 1 to 5 minutes, depending on your server’s internet speed and hardware.

Once completed, you will see the following outcome:

Note you will need to activate the (Rust environment) for your current shell. This is done using the following command to activate the rust environment.

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

Verify the version build of Rust installed, which will show you it is successfully installed.

rustc -V

Example output:

Note, if you cannot print out the version build, you have not activated the Rust environment shell.

Create Rust Sample Project Application

So you have installed Rust and believe it should be working correctly. When installing a programming language on your operating system, the best way to verify is to create a quick test application.

For the tutorial, you will make the famous (Hello World) output using rust.

First, you need to create a directory that will serve as a (Workspace).

mkdir ~/rust-projects

Secondly, change the directory to the Workspace and create a sample application with the following command:

cd rust-projects && nano helloworld.rs

Next, enter the following code for the hello world test:

fn main() {
    println!("Hello World, this is a test provided by LinuxCapable.com");
}

Save and close CTRL+O and then exit CTRL+X then compile the program with the following command:

rustc helloworld.rs

This will create an executable application after it has finished compiling. The application will be in your current directory as the example output below:

ls

Example output:

To run the application you created using Rust, run the program with the execute command:

./helloworld

Example output from the test application as below:

How to Update Rust

To update Rust is relatively easy and is done with a simple command in your terminal. Type in the following:

rustup update

Example output:

How to Remove (Uninstall) Rust

If in the future you no longer require Rust on your system, run the following command:

rustup self uninstall

Example output:

How to Install Rust on Manjaro 21 Linux

You will then get the following result Rust has been successfully removed from your system.

Comments and Conclusion

In the tutorial, you have learned how to install Rust programming language on Manjaro 21 Linux and create a rudimentary test application.

Overall, Rust is fantastic, especially in that it guarantees memory safety. You can’t write buffer overflows, dangling pointers, or double-free bugs in Rust which, instead of C/C++, eliminate a whole class of security bugs in your software.
