Crabs Flying Kites: Writing a Zephyr Application in Rust
summary
Zephyr 4.x now carries initial Rust support and demonstrates that Rust’s ownership model catches data races and use‑after‑free at compile time while leaving performance unchanged. The demo uses Rust + clang + west, requires switching to the west update / main branch because 4.2’s Rust bits are buggy, and builds a static library via the CMake rust_cargo_application glue. A hello world flashed to an inexpensive Wi‑Fi MCU board succeeds, but samples expose stack‑size, alloc/alloc crate and logging caveats — Rust helps, but Zephyr integration remains work in progress.
