Learn Rust for Free
Rust is a systems programming language that gives you control over memory without a garbage collector and without the undefined behavior that trips up C and C++. The borrow checker catches whole classes of memory bugs at compile time, which is why Mozilla, Microsoft, Google, and the Linux kernel now ship Rust in production. This path is for C or C++ developers who want that safety, backend engineers chasing raw performance, and curious programmers who want to understand what memory safety really means. You can build CLIs, web APIs, game engines, and WebAssembly modules with it. Plan for 4 to 8 months part-time starting from zero.
Yes, you can learn Rust for free, and the resources have gotten a lot better in the last few years. Start with freeCodeCamp's 14-hour beginner course to understand ownership and borrowing, reinforce it with Microsoft's free Rust path (which hands you a certificate), then go deep with Google's Comprehensive Rust, a course built for Google engineers and now open to everyone. Rust is a systems language that delivers C-level performance with memory safety, so it fits low-level control, high-performance backends, and WebAssembly. It has topped Stack Overflow's most-admired language ranking every year since 2016. A focused learner reaches a competent level in 4 to 8 months at about 10 hours a week.
Rust was the most admired programming language in the 2024 Stack Overflow Developer Survey, with 83% of developers who use it wanting to keep using it, and it has led that most-admired (formerly most-loved) ranking every year since 2016 (source: Stack Overflow Developer Survey 2024, https://survey.stackoverflow.co/2024/technology/).
Your Step-by-Step Path
Step 1: Programming Foundations
Start with Harvard's CS50 to get comfortable with variables, functions, memory, and how programs actually run. Those ideas carry straight into Rust, which assumes you already know how to program, so CS50 gives you that footing for free before the borrow checker starts asking hard questions.

Step 2: Rust Fundamentals (freeCodeCamp)
freeCodeCamp's Rust course walks through the core ideas Rust is built around: ownership, borrowing, lifetimes, and the borrow checker. At roughly 14 hours it's tight enough to finish over a focused weekend without burying you, and it's the fastest way to see whether Rust clicks for you.

Step 3: Rust Basics with a Certificate (Microsoft Learn)
Microsoft's free Rust path covers similar ground from a different angle, which helps ownership and error handling actually stick the second time around. It also ends with a verifiable certificate, and the Microsoft badge is worth putting on a CV or LinkedIn when you're job hunting.

Step 4: Comprehensive Rust (Google)
This started as Google's internal Rust training for experienced engineers and is now open-sourced and free. It takes you from 'I understand basic Rust syntax' to 'I can write real Rust', covering the full language including unsafe Rust, concurrency, and async. Finish this and you can build production code.

Frequently Asked Questions
Is Rust a good first programming language?
Not really. Rust's borrow checker enforces rules that make a lot more sense once you already understand variables, memory, and pointers, so most people bounce off it as a first language. Start with Python or JavaScript to learn the fundamentals, then come to Rust once code feels natural.
How long does it take to learn Rust?
Plan for 4 to 8 months part-time from a standing start to reach a competent level. If you already know C or C++, expect closer to 2 to 4 months, since you understand memory and pointers and only need to learn Rust's rules for managing them safely.
What can I build with Rust?
A lot. Command-line tools (with clap and serde), web servers and APIs (Axum or Actix), game engines (Bevy), WebAssembly modules that run in the browser, and low-level system utilities. Rust compiles to fast single-binary executables, which makes it a strong pick for tooling and infrastructure.
Why is Rust hard to learn?
The borrow checker enforces memory-safety rules at compile time that most languages either defer to runtime or ignore entirely, so the compiler rejects code that would work elsewhere. It feels like fighting the compiler at first. For most people it clicks after a few weeks, and then those same rules stop you shipping whole categories of bugs.
Do I need to know C or C++ before learning Rust?
No, but a general programming background helps, because Rust assumes you already grasp memory, functions, and data structures. You don't need C or C++ specifically. Harvard's CS50, the first step on this path, covers the foundations you need if you're starting fresh.
