Great! Thank you for this clarification.

Also incompatable -> incompatible ?

Nitpick: should contain both the major...

But that's just me.

I would also use @code{rust-clap-2} and @code{rust-rand-0.6}

@xref is misused here. It targets references at the beginning of
a sentence. I.e., it will generate

  ... other packages the See cargo-build-system presents...

I suggest the more verbose

  ... other packages the Cargo build system (@pxref{cargo-build-system}) presents...
