Unwrap()Ing Rust on Embedded Linux
summary
Company migrates C to Rust progressively one file at a time, using C FFI via build.rs and the cc crate and keeping reproducible cross builds with cross (cross-rs). For Yocto use either meta-rust (builds compiler from source) or meta-rust-bin (prebuilt toolchain) depending on speed and distro. Measure size with cargo-bloat: initial hello world drops from ~4.4 MB to ~372 KB with stripping and size opts, going no_std can yield ~16 KB binary or 1.2 KB code section. Tests run from unit to qemu integration.
