Hey Alex, you can follow the instructions here:

https://wiki.debian.org/Teams/RustPackaging#Porting_to_a_new_architecture

Note that the page talks about cross-compiling rustc and cargo, but the process is exactly the same for other packages, just use e.g. "rust-ripgrep" in place of $pkg in those instructions instead of "rustc" or "cargo".

You will need to first follow the setup instructions here: https://wiki.debian.org/sbuild
