What is Rust Programming: A Beginner's Guide

If you've made your way here, you're probably curious about Rust programming. Maybe you've heard about it from a friend, or you've stumbled upon it while involved in other development projects.

Either way, you're in the right place. In this article, we're going to dive into the world of Rust programming. We'll cover what it is, why it's a popular choice, and how you can get started.

Let's begin.

What is Rust?

What is Rust

Rust, a programming language that embraces multiple paradigms, has been making waves in the tech world recently. Its core principles revolve around speed, safety, and the ability to handle multiple tasks concurrently. In essence, Rust is engineered to supercharge your software, bolster its security, and multitask like a pro.

Pretty impressive, isn't it?

But wait, there's more. Rust takes a firm stand on memory safety. This process guarantees that all memory references are valid, thereby eliminating the need for garbage collection or reference counting commonly used in languages that prioritize memory safety, according to the openSUSE.

The result? You get to craft code that's not only swift and secure but also optimized for efficiency.

Why is Rust Popular?

Rust is not just another programming language. It's a breath of fresh air in the world of programming. The language has fewer downsides compared to others and effectively resolves common issues.

We'll dive into its specific features more in a moment, but as a brief overview, its emphasis on memory safety means you can write high-performance code without worrying about memory leaks or other common bugs. Plus, Rust's strong type system and ownership model help catch bugs at compile-time, before your code even runs.

And it's not just us saying this. Rust has been voted the most loved language by developers in the Stack Overflow Developer Survey for four years running back in 2020 -- a survey which involved nearly 65,000 developers.

Key Features of Rust

Rust is packed with features that make it a joy to use. Here are some of the highlights:

Memory Safety

As we already mentioned, Rust stands out for its emphasis on memory safety. Unlike other memory-safe languages that use garbage collectors or reference counting, Rust ensures that references always point to valid memory. This allows you to write code that is not only fast and secure, but also efficient.


Handling multiple tasks at the same time is a must in most development situations, and Rust shines in this department. Rust's approach to concurrency is one of its most powerful aspects, helping you write code that's fast, safe, and concurrent without the headaches typically associated with multithreaded programming.


Rust doesn't just aim to make your code safe —it also aims to make it fast. Rust code compiles to machine code, meaning it's designed to take full advantage of your hardware.

Plus, Rust's zero-cost abstractions ensure that you don't pay any performance cost for using high-level features.

Type System and Ownership Model

Rust's type system and ownership model are at the heart of its approach to safety and concurrency. The ownership model, in particular, is a unique feature of Rust, allowing fine-grained control over memory management and helping prevent common programming errors like null pointer dereferencing and data races.

These features make Rust a powerful tool in your programming toolbox. Whether you're building a high-performance web server, a system utility, or a game, Rust has the features and ecosystem to make your project a success.

But nothing is without its potential drawbacks, so we'll explore that aspect next.

The Downsides of Rust

While Rust has many strengths, it's not without its challenges. Here are a few things that might trip you up:

Steep Learning Curve

Rust is known for its steep learning curve. It introduces several new concepts, such as ownership, borrowing, and lifetimes, which can be difficult to grasp, especially for beginners. But don't let this discourage you. The Rust website team has put together excellent resources to help you learn, and with time and practice, these concepts will start to click.

Plus, they have an active community of dedicated developers that answer questions and help each other out all the time. There's a forum, a Discord, email newsletter, and more for getting up to speed.

Rust's focus on explicitness and safety can sometimes lead to verbose code. This is especially noticeable when compared to languages like Python or JavaScript, where you can often do a lot with just a few lines of code. However, this verbosity also makes Rust code very explicit, which can be a boon when debugging or working in large codebases.

Smaller Ecosystem

While the Rust ecosystem is growing rapidly, it's still smaller than those of more established languages like JavaScript, Python, or Java. This means you might not always find a library or framework for the specific task you're working on. Even so, the quality of the available Rust libraries is generally very high, and the community is constantly working to fill in the gaps.

Compile Times

Rust's focus on zero-cost abstractions, safety, and concurrency comes at a cost: compile times. Rust's compiler does a lot of work to ensure your code is safe and fast, but this can lead to slower compile times compared to other languages. This is a common complaint within the Rust community, and efforts are being made to improve this.

Despite these challenges, many developers find that the benefits of Rust outweigh the downsides. The safety, performance, and concurrency that Rust provides can be a game-changer, especially for system-level programming. And while the learning curve is steep, the investment can pay off in the long run.

The Rust Ecosystem

The Rust ecosystem is vibrant and growing. There are libraries (called "crates") for just about everything you can think of, from web development to game development. The package manager, Cargo, makes it easy to manage your project's dependencies. And the documentation. Well, let's just say, It's some of the best you'll find in any programming language.

But it's not all roses in the world of Rust. Like any language, Rust has its challenges. The learning curve can be a lot, especially if you're new to systems programming. But the community and educational resources make it a manageable effort, from the official Rust book to countless tutorials and blog posts.

Getting Started with Rust

Ready to dive in and start coding with Rust? Great! Here's how you can get started:

1. Install Rust

The first step to starting with Rust is to install it on your machine. You can download Rust from the official website. It's available for Windows, macOS, and Linux. The installation process is straightforward, and the website provides detailed instructions for each operating system.

2. Set Up Your Development Environment

Next, you'll want to set up your development environment. While you can use any text editor or Integrated Development Environment (IDE) to write Rust code, some tools offer excellent support for Rust. Visual Studio Code with the Rust extension is a popular choice.

It provides features like auto-completion, syntax highlighting, and formatting that can make your coding experience smoother.

3. Learn the Basics

Now that you've got Rust installed and your development environment set up, it's time to start learning! Rust Programming Book is an excellent place to start. It's comprehensive, easy to understand, and best of all, free! It covers everything from the basics to more advanced topics like concurrency and error handling.

4. Write Your First Program

Once you've got a handle on the basics, it's time to start coding! A traditional first program to write is "Hello, World!". In Rust, it's as simple as:

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

This program will print the text "Hello, World!" to the console. It's a simple program, but it's a start!

5. Practice Coding

The more you code, the better you'll get. Try solving problems on coding platforms like Exercism or LeetCode. These platforms offer problems of varying difficulty levels, allowing you to gradually increase your skills.


6. Explore and Build

Finally, start a project! Whether it's a simple command-line tool or a web server, building something from scratch is a great way to consolidate your learning and gain practical experience.
