+@subsubsection Common Workflow for Updating Existing Rust Packages
+
+For this example, we'll update @code{niri}. The package definition looks like
+this initially:
+
+@lisp
+(define-public niri
+  (package
+   (name "niri")
+   (version "25.08")
+   (source (origin
+             (method git-fetch)
+             (uri (git-reference
+                   (url "https://github.com/YaLTeR/niri")
+                   (commit (string-append "v" version))))
+             (file-name (git-file-name name version))
+             (sha256
+              (base32
+               "09nsxd211mly8r1ys2lq6ia4jxgb980h1axrbgw748r0knfbbj7n"))))
+   (build-system cargo-build-system)
+...
+@end lisp
+
+We start by running the usual @command{guix refresh -u niri}.
+
+The @command{-u} flag will update in place the version and hash for the
+@code{niri} package.
+
+The package definition will then look like this:
+
+@lisp
+(define-public niri
+  (package
+   (name "niri")
+   (version "25.11")
+   (source (origin
+             (method git-fetch)
+             (uri (git-reference
+                   (url "https://github.com/YaLTeR/niri")
+                   (commit (string-append "v" version))))
+             (file-name (git-file-name name version))
+             (sha256
+              (base32
+               "0752qm245wc2gak0jhp0fnr0rdj3z54m2h97k3cxbjym9pcn658n"))))
+   (build-system cargo-build-system)
+...
+@end lisp
+
+This means the source field was updated successfully, thus we can now proceed to
+get the updated source with @command{guix build --source niri} as follows:
+
+@example shell
+$ cp -r $(./pre-inst-env guix build --source niri) /tmp
+$ cd 8frb34ffybxshq4146nz68zbv7fljk45-niri-25.11-checkout/
+@end example
+
+@quotation Note
+In this specific example, the source is a git checkout, thus a directory. If the
+package source is a compressed archive, you would at this point extract it to a
+directory to proceed.
+@end quotation
+
+Now, given that we have access to the @code{Cargo.toml} file, we can now run
+the following inside the checkout:
+
+@example shell
+$ guix shell rust rust:cargo -- cargo generate-lockfile
+$ guix shell rust rust:cargo -- cargo audit
+$ guix shell rust rust:cargo -- cargo license
+@end example
+
+@quotation Note
+Sometimes, the package will require a more up-to-date version of rust, that is
+not yet the default rust on guix. For these cases you can use:
+@example shell
+$ guix shell -e "(@ (gnu packages rust) rust-1.90)" \
+     -e '`(,(@ (gnu packages rust) rust-1.90) "cargo")'
+@end example
+@end quotation
+
+The first command will ensure that all cargo dependencies are up to date
+and semver compatible, while also providing some other benefits, as further
+explained in @ref{Common Workflow for Rust Packaging}.
+
+The following command will warn if there are any known vulnerabilities in the
+crates being imported, and the latter will output the license information of all
+the dependent crates.
+
+If everything looks good, we can now replace the contents of the
+@code{niri} indentifier, inside @code{lookup-cargo-inputs} on
+@code{gnu/packages/rust-crates.scm}, with the newer updated crates by running
+the importer on the lockfile as follows:
+
+@example shell
+$ guix import -i /path/to/gnu/packages/rust-crates.scm \
+     crate -f Cargo.lock niri
+@end example
+
+@quotation Note
+For the purpose of contributing a package to Guix (@pxref{Contributing,,, guix, GNU Guix Reference Manual}),
+there is no need to cleanup the leftover crates as a result of the
+package update.  This is tasked to the rust-team (@pxref{Teams,,, guix, GNU Guix Reference Manual})
+to periodically run a convenient script in @code{etc/teams/rust} to cleanup
+unused crates from @code{gnu/packages/rust-crates.scm}.
+@end quotation
+
+After that, we look at @code{gnu/packages/rust-crates.scm} and check if there
+are any TODO's generated by the importer. In our example, there are a few
+occurrences like so:
+
+@lisp
+(define rust-libdisplay-info-sys-0.3.0
+  ;; TODO: Check bundled sources.
+  (crate-source "libdisplay-info-sys" "0.3.0"
+                "07xmkc2aqcdn6d58321y87rd3gzdr4nx3ncm1mmrr7w1p1ahsn96"))
+
+(define rust-smithay-0.7.0.d743e1a
+  ;; TODO: Define standalone package if this is a workspace.
+  (origin
+    (method git-fetch)
+    (uri (git-reference (url "https://github.com/Smithay/smithay.git")
+                        (commit "d743e1a317fa0f01d1c4cadd96d277a1ec7b59d9")))
+    (file-name (git-file-name "rust-smithay" "0.7.0.d743e1a"))
+    (sha256 (base32 "11327mhxxf844bs0v5bw1g9bzjssnzhidsissywy6kwng16x727v"))))
+@end lisp
+
+We then check the first for bundled sources, and since there are none, we remove
+the TODO line. Continuing, after verifying that the latter is not a workspace,
+we also remove its TODO line.
+
+If there were any problems, we would patch the crates with snippets, and then
+also remove the TODO line after solving the problem.
+
+We then try to build the package with @command{guix build niri}, and make sure
+if it builds successfully, which it does.
+
+As a good practice, we can further check the output of the
+@code{check-for-pregenerated-files} phase to ensure there are no extraneous
+pregenerated files inside the crates. If there are any, it is important to
+snippet them out like so:
+
+@lisp
+(define rust-winapi-x86-64-pc-windows-gnu-0.4.0
+  (crate-source "winapi-x86_64-pc-windows-gnu" "0.4.0"
+                "0gqq64czqb64kskjryj8isp62m2sgvx25yyj3kpc2myh85w24bki"
+                ;; This removes a bunch of ".a" pregenerated binaries
+                ;; that were hinted on the check-for-pregenerated-files
+                ;; phase.
+                #:snippet '(delete-file-recursively "lib")))
+@end lisp
