Moving to modern languages in long-living projects
summary
Rewrites parts of a 12‑year‑old libvirt codebase into Rust as a proof‑of‑concept, picking an isolated module from a generated call graph and incrementally replacing C with Rust. Uses rust-bindgen (invoked from build.rs), cargo vendor for offline builds, c2rust/corrode for exploration, and minimal unsafe minimized wrappers with #[no_mangle] extern "C" interfaces. Tests validate FFI behavior; basic functions (file creation, string return) work, but allocator/panic hooks require nightly and more integration work remains.
