I'm not sure why this is counter-intuitive. The existence of any rust at
all means you need to build rust code. The normal way to do that in Guix
is to use the cargo-build-system.

Equally, I don't find it strange that the upstream build instructions[1]
ask me to install a rust compiler and cbindgen. I need to do that if I
want to build rust code.

It's also worth noting that there are 22 packages in Cargo.lock[2], so
building the one rust file in the repository is a bit more involved.
