Every way to learn

Read, listen, test yourself, ask the AI, or look up anything you've already covered. Every lesson meets you where you are.

Intro to Variables
Audio

A variable is a named container that stores a value you can reference later in your program.

In Python, you create one by writing the name, an equals sign, then the value you want to store.

The value can change over time - reassigning the name simply points it to a new value.

Why learn Rust with Coddy

  • Write and run real Rust code in your browser. No rustup install, no Cargo setup. Each lesson compiles your Rust program server-side and shows the output (and any compiler errors) instantly.
  • What makes Rust unique: ownership, borrowing, lifetimes, traits, enums and pattern matching, error handling with Result. The Rust foundations every systems programmer needs.
  • AI hints walk you through Rust's famously strict compiler errors, so the borrow checker becomes a teacher instead of a wall when you're getting started.
  • Free Rust certificate when you finish the course. A credible signal for systems, infrastructure, blockchain, and embedded roles where Rust is increasingly the language of choice.

Frequently asked questions about learning Rust

Is Rust hard to learn?

Rust has a reputation for being hard, mostly because of ownership and the borrow checker - concepts most other languages don't expose. The flip side is that the compiler catches a huge class of bugs at build time. The course introduces ownership and borrowing gradually, with small exercises that turn the borrow checker from a wall into a teacher.

What is Rust used for?

Systems programming, infrastructure (parts of the Linux kernel, Cloudflare, Discord, Dropbox), command-line tooling, embedded work, WebAssembly, and a growing chunk of blockchain and crypto code. It targets the same niches as C and C++ but with much stronger safety guarantees.

How long does it take to learn Rust?

Rust basics - syntax, control flow, functions, structs, enums - take two to four weeks of daily practice. Becoming comfortable with ownership, borrowing, lifetimes, and traits usually takes another two to six months. Mastery (advanced lifetimes, async, unsafe Rust) is a longer arc and best driven by real projects.

Should I learn Rust or Go?

Both are modern, statically-typed languages aimed at servers and infrastructure, but they trade off differently. Go optimizes for fast compile times, simple concurrency, and small spec - easier to pick up. Rust optimizes for performance and memory safety without a garbage collector - harder to learn but goes lower-level. Pick Go for backends and cloud tooling; pick Rust for systems work, performance-critical code, or anything that used to be C/C++.

Can I learn Rust online for free?

Yes. The interactive Rust course is free - full lessons, coding exercises, quizzes, and a certificate. Rust compiles server-side, so you don't need to install rustup or Cargo locally to get started writing real Rust.

Do I get a certificate after the Rust course?

Yes. Finishing the Rust course gives you a free certificate of completion. A verifiable signal you can add to your resume or share on LinkedIn alongside any Rust projects, CLI tools, or open-source contributions you've built.
