It is possible to use Rust shared objects in C (and other languages) with the "cdylib" or "staticlib" crate types and when the Rust functions are marked with 'extern "C"'. See https://docs.rust-embedded.org/book/interoperability/rust-wi... and https://doc.rust-lang.org/reference/linkage.html. The YouTube video https://www.youtube.com/watch?v=5zmaLhSAkNE has an example/demo and Jon Gjengset has the "Reverse FFI" section in his "Crust of Rust: Build Scripts and Foreign-Function Interfaces (FFI)" video at 2:02:57 https://www.youtube.com/watch?v=pePqWoTnSmQ&t=7378s. Finally, https://prog.world/building-and-using-dynamic-link-libraries... is yes another article on "Building and using dynamic link libraries in Rust".
