How does rustc find the (Rust) dependencies when building a package in cargo-build-system? There doesn't seem to be a RUST* or CARGO* environment variable or anything when I do "guix environment rust-c-vec --fallback". (Note that I picked rust-c-vec to fix first because it has only rust-libc as dependency) I read that there are actual Rust binary libraries, seldomly used, and everything-included-only-as-source otherwise. How do I specify which it is? Or is that not implemented yet? I tried specifying the latter as native-inputs - which doesn't seems to work either...
