À la carte: mix and match C, Rust and Go!
summary
Practical recipe and working code for replacing or mixing a C library with Rust or Go: a small toy name builder library implements objects, callbacks and error reporting and the repository contains a working implementation. Uses bindgen + Cargo build.rs to generate Rust bindings, cgo lookup table trick to pass Go callbacks to C, and boxed pointers for C↔Rust object handles. Two surprising lessons: calling Go from C is uncommon but possible, and most glue code is mechanical and suitable for code generation; examples work but aren’t production-tested.
