Unwrap()Ing Rust on Embedded Linux
summary
Company migrates an embedded Linux codebase from C to Rust over 18 months using cross for reproducible cross‑compiles and Yocto with either meta‑rust or meta‑rust‑bin for image builds. Migration goes file‑by‑file with C↔Rust FFI via build.rs, cc and cmake crates; tests run as unit tests plus qemu integration. Binary size shrinks from ~4.4 MB to ~372 KB by stripping and removing the panic handler, and to ~16 KB with no_std; cargo bloat identifies the ~258 KB stdlib cost.
