The Case for Learning Rust Before Your Next Side Project

Everyone recommends Python for side projects. It’s fast to write, has great libraries, and gets out of your way. For most hobby builds, that’s the right call. But there’s a case for going the other way: learning Rust before your next side project, even—especially—if you’ve never used it. The learning curve is steep. The payoff is a different kind of thinking.

Here’s the pitch: Rust forces you to confront memory, ownership, and concurrency before they bite you in production. You’ll write slower at first. You’ll fight the borrow checker. And then you’ll ship a side project that doesn’t segfault, leak memory, or race. For a language designed for systems programming, Rust has become surprisingly practical for the kind of tools indie makers love to build: CLI utilities, small services, embedded projects. The question isn’t whether Rust is worth learning. It’s whether your next project is the right place to start.

Why Rust for Side Projects

Side projects are low stakes. No deadlines, no stakeholders, no legacy codebase. That makes them ideal for learning. When the borrow checker blocks you for an hour, you’re not blocking a team. When you rewrite a module three times to get the types right, nobody’s waiting. The low-stakes environment is exactly where you can afford to learn something hard.

Rust also produces tools that feel native. A Rust CLI compiles to a single binary—no Python interpreter, no Node runtime. It starts fast, uses little memory, and runs anywhere. For the kind of utilities indie makers build—file converters, automation scripts, small web servers—that matters. Users don’t want to install a runtime. They want a binary that works.

The Learning Curve Is Real

Rust is not Python. Ownership, borrowing, lifetimes—these concepts don’t exist in most languages. You’ll hit walls. “Why can’t I do this?” will be a recurring question. The answer is usually: because Rust is preventing a bug you haven’t seen yet. A use-after-free, a data race, a double-free. The compiler is strict because the problems it prevents are subtle and nasty.

The curve flattens. After a few weeks, the borrow checker stops feeling adversarial. You start writing code that compiles on the first try. The habits Rust teaches—thinking about who owns data, when it’s borrowed, how long it lives—carry over to other languages. You’ll write better C, better Go, better Python. The investment pays dividends beyond Rust itself.

What Kind of Side Project Fits Rust

Rust shines for performance-sensitive tools, system utilities, and long-running services. A CLI that processes millions of lines. A small HTTP server that handles thousands of requests. An embedded project on a microcontroller. If your project touches the OS, the network, or raw data—Rust is a strong fit.

Rust is overkill for a quick script or a prototype. If you need to ship something in a weekend, reach for Python or TypeScript. Rust rewards patience. Save it for projects where correctness and performance matter, and where you’re willing to spend time getting the foundations right.

The Ecosystem Is Ready

Rust’s ecosystem has matured. Cargo, the package manager, is excellent. Crates.io has libraries for almost everything—HTTP, async, parsing, serialization. The async story is solid. You can build a production-ready web service with Actix or Axum, a CLI with Clap, a database client with SQLx. The days of “Rust has no ecosystem” are over.

The community helps. Rust’s documentation is outstanding. The Rust Book is free and thorough. Error messages are famously helpful. When you’re stuck, the answer is usually a search away. Learning Rust in 2026 is easier than it was in 2019.

The Bottom Line

Learning Rust before your next side project isn’t for everyone. If you want to ship fast, pick a language you already know. But if you’re ready to invest in a different way of thinking—one that prevents whole classes of bugs and produces fast, reliable tools—Rust is worth the climb. Your next side project might be the perfect place to start.
