@veer66 you'll want to check https://wiki.debian.org/Gnome/Rust_Packaging to package a standalone Rust program. You can check e. g. tex-fmt for a simple example. Feel free to ask on the #debian-rust IRC channel in case you have any questions

@veer66 yes, the wrapper mentioned on the wiki page works for .so files too. You can take a look at the glycin package in Debian. If you have any questions feel free to ask
