cargo/rust is poorly integrated in Guix, as there's some impedance
mismatch between package handling by Guix and Cargo itself, which would
rather take care of it.

I'd expect most Rust developpers using Guix only do so to provide
Rust/Cargo, and let Cargo take care of the rest.  Otherwise you'd need
to replicate the pain the cargo-build-system goes through to make it
work.

A more future-proof approach if you'd like to improve Rust integration
into Guix would be to continue integrating the 'antioxydant' build
system effort started by Maxime Devos [0], which doesn't rely on Cargo
to build Rust crates (and supports dynamic linking of Rust libraries, I
think?).
