Hi,

These patches add new cargo utility to audit the security of rust crates.

Maybe it could be integrated into the guix lint command to increase the auditing of rust ecosystem in GNU Guix.

However, I do see one downside as this would create coupling on rust which might be problematic e.g. on Aarch64 architecture and it would also increase the complexity and build time for guix package.

Nevertheless it can be used on it's own.
