Hi everyone,

Chris and I had a very productive discussion around this patch series =
this
evening. We discussed an alternative approach to allowing the =
cargo-build-system
to capture all transitive Rust crate sources without changing the =
established
semantics around Guix inputs and native-inputs.

The short summary is introducing crates as new arguments in the package
definition. These arguments will be expanded to include the sources of =
any
transitive sources when lowered to a derivation, while preserving any
other Guix inputs/native-inputs the package may wish to include.

I'll be sending an updated patch series here once I get a chance to work =
on
this, and I=E2=80=99ll elaborate on the solution with more specifics =
then!

Thanks,
--Ivan=
