Python has served you well: you spun up a prototype and iterated quickly, keeping up with the evolving requirements of a successful product. Nonetheless, as time goes on, cracks are starting to show up: an endpoint is slower than it needs to be, a data processing job that took seconds now takes almost an hour, and your infrastructure bill is growing too fast compared to the size of your user base. Engineers are starting to whisper: is it time for a rewrite? Should we pause feature development to rebuild everything on more solid foundations? That's an option, but it's expensive.

There's another path: rather than throwing away your entire Python codebase to start over, you analyse your application and isolate the performance-critical bits—the so-called "hot modules" where your application spends most of its time. You will rewrite those in Rust and package them as a Python native extension. This workshop will teach you how.

We will cover the pyo3 crate, the subtleties of Python's Global interpreter lock, and typical examples that may arise in your daily Rust-Python interoperability work. By the end of the session, you will be well-equipped to seamlessly replace your slow Python modules with easy-to-use and blazingly fast Rust modules.

We assume you are familiar with Rust and Python, but we don't assume any prior interoperability knowledge. We will provide a brief explanation and references whenever we rely on advanced features in either language.

Rust is the future of embedded software. No matter if you’re developing robust embedded systems, creating low-power, secure IoT products, or taking your device to space, Rust revolutionizes embedded software engineering. In this workshop, you’ll learn to apply your embedded engineering skills to the modern, ergonomic, performant, and memory safe programming language that is Rust. You’ll get acquainted with Rust’s embedded ecosystem, widely used tooling, and work your way from the basics to writing complex, multitasking applications.

Furthermore, this workshops covers the current state of art when it comes to using Rust in safety-critical systems with real-time requirements.

At the end of this workshop, you will be able to build robust and secure (asynchronous) embedded applications in Rust, write platform-agnostic device drivers, and work with tools and frameworks that are widely used in Rust's embedded ecosystem. On top of that, you know what to consider when it comes to using Rust in safety-critical systems.

This workshop is targeted at experienced embedded developers that want to learn embedded development in Rust. Limited knowledge of Rust is assumed, but you are assumed to be proficient in low-level embedded software engineering in C or C++.

We will work with real hardware during this workshop.
