@xref{Packaging Rust Crates,,, guix-cookbook, GNU Guix Cookbook}, for
packaging workflow.
@subsubsection Commit messages
The commit message must have a general brief mention to entry changes
in @code{(gnu packages rust-crates)}. For changes in @code{(gnu packages
rust-sources)}, the commit message must explicitly mention all changes to the
packages.
Here are some examples for different situations:
@itemize

@example
