I'm a bit confused about what you exactly mean. Can you provide an
example? Programmatically, the build-system isn't supposed to be
reflected (package components of the build-system) in the inputs fields
of packages, Rust is no different.

The typical way of creating Rust crate definitions is to use `guix
import crate <package-name-on-crates.io>' to obtain a template
definition that you'd refine after building and testing the package. If
the crate is not hosted on crates.io, then you would have to read the
`Cargo.toml' file for build instructions. The guix import command also
has a '--recursive' option to automate that process for all the
dependencies of a crate as well. It's a repetitive process for sure, but
you don't have to find out dependencies by build errors.
