Introduction to Rust: Why You Should Start Right Now

The Rust programming language has been recognized as one of the most beloved among developers for several years in a row. In 2025, it has firmly established itself in the top tier of languages for systems programming, web development, and even game development. Its main advantages are incredible performance on par with C/C++ and absolute memory safety without a garbage collector. Companies like Microsoft, Google, Amazon, and Mozilla are actively adopting Rust in their projects.

If you are a beginner and want to enter the world of modern programming, Rust is an excellent choice. In this article, we will break down where to start learning Rust in 2025: from installation to your first meaningful project.

Installing and Setting Up the Rust Environment

Installation via rustup

The simplest and recommended way to install Rust is to use the official tool rustup. It allows you to manage compiler versions and install necessary components.

For installation on Linux and macOS, open a terminal and run:

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

For Windows, download the installer from the official website and run it.

After installation is complete, check the compiler version:

rustc --version

You should see something like:

rustc 1.79.0 (2025-02-15)

What is Included in the Standard Installation

rustc — the Rust compiler.
Cargo — the build system and package manager (similar to pip for Python).
rustup — a utility for updating and managing tools.
rust-docs — local documentation.

You can update the installation to the latest version with the command:

rustup update

Creating Your First Rust Project

In Rust, it is not common to write code in a single file (although it is possible). Instead, you create a project using Cargo. This provides a ready-made folder and file structure.

Command for a New Project

cargo new hello_rust

This command will create a folder hello_rust with the following structure:

hello_rust/├── Cargo.toml└── src/    └── main.rs

The file Cargo.toml is the project manifest (similar to package.json or requirements.txt). The file src/main.rs is the program's entry point.

Writing "Hello, World!"

Open the file src/main.rs and replace its contents with:

fn main() {    println!("Hello, world! Learning Rust in 2025!");}

Now build and run the project with a single command:

cargo run

You should see in the terminal:

   Compiling hello_rust v0.1.0 (path/to/project)    Finished `dev` profile [unoptimized + debuginfo] target(s) in 0.23s     Running `target/debug/hello_rust`Hello, world! Learning Rust in 2025!

Congratulations! You have just written and run your first Rust program.

Rust Syntax Basics for Beginners

Let's break down the key concepts you need to know at the very beginning.

Variables and Immutability

By default, all variables in Rust are immutable. This is one of the language's main features, ensuring safety.

fn main() {    let x = 5;          // immutable variable    // x = 6;          // ERROR: cannot mutate immutable variable    println!("x = {}", x);

    let mut y = 10;     // mutable variable (keyword mut)    y = 20;    println!("y = {}", y);}
