Porting Embassy to a Rust-based embedded Operating System - Dănuț Aldea | EuroRust 2025

Porting Embassy to a Rust-based embedded Operating System - Dănuț Aldea at EuroRust 2025 This talk explores the integration of two Rust-based embedded systems concepts: Embassy, an async runtime designed for low level development, and TockOS, a secure, capability-based operating system designed for safety-critical applications. We’ll walk through the motivation and challenges behind porting Embassy’s async executor to run in userland processes on Tock and how we adapt embassy’s executor model to work within Tock’s strict isolation and syscall architecture. Whether you’re building secure IoT systems, exploring Rust for embedded development, or interested in OS design, this talk will highlight what it takes to bring modern async programming together with a robust microkernel. The result is a safer, more composable foundation for concurrent embedded applications. About Dănuț Aldea I am a computer engineer with a passion for systems programming, embedded development, and open-source. I enjoy working with Rust and exploring how low-level software interacts with hardware efficiently, reliably, and securely. -------------------- EuroRust 2026 – Get your ticket for EuroRust 2026 now and join us in Barcelona! 👉 https://eurorust.eu EuroRust is organized by Mainmatter, experts in Rust and distributed systems 👉 https://mainmatter.com/rust/
