How to Install Rust Programming Language on Fedora 34 / 35

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.

For users, especially developers wanting to try out Rust Programming language, you will know how to install Rust Programming Language on Fedora 34 / 35.

Prerequisites

  • Recommended OS: Fedora Linux 34 / 35 or higher.
  • User account: A user account with sudo or root access.

Updating Operating System

Update your Fedora operating system to make sure all existing packages are up to date:

sudo dnf upgrade --refresh -y

Install Dependencies Required

Before you proceed to the installation of Rust, run the following command to install or check that the packages below are installed or are up to date. Failure to do this may result in Rust not being installed correctly on your Fedora system.

sudo dnf install curl dnf-plugins-core install cmake gcc clang make -y

Once installed, proceed to the next part of the tutorial of installing Rust.

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

You should see an output like the example below. “Type 1” and hit “Enter Key” to continue.

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:

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

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

Verify the version build of Rust installed, which in turn will show you it is successfully installed as well. Type the following command and hit enter:

rustc -V

Example output (This will change in time with newer versions):

rustc 1.55.0 (c8dfcfe04 2021-09-06)

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

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

WARNING: DO NOT USE SUDO OR ROOT TO CREATE THE RUST PROJECT DIRECTORIES OR FILES, OR YOU WILL HAVE ISSUES COMPILING.

mkdir path/to/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:

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 operating system, run the following command:

rustup self uninstall

Example output:

How to Install Rust Programming Language on Fedora 34 / 35

To successfully remove, type “Y” and press the “ENTER KEY”.

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

Comments and Conclusion

In the tutorial, you have learned how to install Rust programming language on your Fedora operating system 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.
