Why Rust and Zephyr Are a Good Fit
summary
Project enables writing Zephyr applications entirely in Rust with only 20 lines of glue and full cargo integration works so cargo builds crates inside Zephyr CMake. Bindings expose timers, mutexes, threads, work-queues and a generated device-tree-as-Rust-modules approach. An embassy-based executor runs on Zephyr (small implementation) and real apps boot on hardware; a personal keyboard moved from saturating CPU to mostly idle after converting to async. Missing pieces: async awaiting on Zephyr primitives, more driver wrappers and user‑space support.
