It's not pretty currently using guix's crates. The first part, getting
the necessary crates, involves manually adding them (with their
dependencies!) to your environment. The second part involves adjusting
your config.toml to include the following:
[source.crates-io]
local-registry = '/gnu/store/3nfgfhxlciblr360jyrgxl275sf78a6f-profile/share/cargo/registry'
HOWEVER, instead of /gnu/store/...-profile you need to adjust the path
to the value of your GUIX_ENVIRONMENT, and there's no way that I've
figured out to use $GUIX_ENVIRONMENT in a toml file.
Actually, it looks like I have the cargo registry patches sitting
unapplied on my machine, so I'm not even sure if it'll work the way I
wrote above. I'll see about getting them into a state I'm happy with
for the rust-team branch.

(package): Obtain output from 'cargo manifest' of the current package
when the package will be installed.
(install): Don't install cargo crates and source.
(install-source): New phase. Install cargo crates. Generate cargo
registry index files and install them in a known location.
(%standard-phases): Add 'install-source phase after 'install.
