Rust Installation and First Project

What is Rust?

Rust is among the fast, safe, and concurrent programming languages. Especially preferred for low-level system software, Rust stands out with its memory safety features. In this article, you will learn how to install Rust and how to create your first project.

Rust Installation

Installing the Rust programming language is quite simple. To begin, we will use Rust’s official installer tool. Type the following command into your terminal or command prompt:

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

This command will install the latest version of Rust on your computer. After installation, update the PATH environment variable to make Rust ready to use. After the installation is complete, to check if Rust is installed:

rustc --version

Run this command. If Rust was successfully installed, you will see the version number.

Your First Rust Project

Now that Rust is installed, let’s create our first project. By following the steps below, we will develop a simple "Hello, World!" application.

Creating the Project

To create a new project, run the following command in the terminal:

cargo new hello_rust

This command will create a new folder named hello_rust and a basic project structure. Go to the created directory:

cd hello_rust

Now open our main file, src/main.rs, and write the following code inside:

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

Running the Application

Now we are ready to run our project. You can start your application by running this command in the terminal:

cargo run

This command will compile and run your project. If everything was done correctly, you should see the message "Hello, World!" in the terminal.

Conclusion

In this article, you learned how to install Rust and how to create your first simple project. Rust is an excellent choice for developers looking for a powerful and reliable language. As you develop your applications, you will discover many features that Rust offers.
