Getting Started with Rust - A Beginner's Guide

Rust is a systems programming language that runs blazingly fast, prevents segfaults, and guarantees thread safety. In this guide, we'll walk through the basics of getting started with Rust.

Why Rust?

There are several reasons why Rust has become so popular:

• Memory Safety - No null pointers, no dangling pointers, no buffer overflows
• Zero-cost abstractions - High-level features without runtime overhead
• Fearless concurrency - Write parallel code without data races

Installation

The easiest way to install Rust is through rustup:

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

After installation, verify it works:

rustc --version
cargo --version

Your First Program

Let's write the classic "Hello, World!" program:

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

Save this as main.rs and compile it:

rustc main.rs
./main

Using Cargo

For real projects, you'll want to use Cargo, Rust's package manager:

cargo new my_project
cd my_project
cargo run

Tip: Cargo handles dependencies, building, testing, and more. Always use Cargo for anything beyond simple examples.

Conclusion

Rust has a steep learning curve, but the payoff is worth it. You get the performance of C/C++ with the safety guarantees of higher-level languages.
