Wow! Nice.

Review below:

"installs"

+             (setenv "LLVM_LINK_SHARED" "1")

+         (add-after 'patch-source-shebangs 'patch-cargo-checksums
+           (lambda* (#:key inputs #:allow-other-keys)
+             (substitute* "src/Cargo.lock"
+               (("(\"checksum .* = )\".*\"" all name)
+                (string-append name "\"" ,%cargo-reference-hash "\"")))
+             (for-each
+              (lambda (filename)
+                (use-modules (guix build cargo-build-system))
+                (delete-file filename)
+                (let* ((dir (dirname filename)))
+                  (display (string-append
+                            "patch-cargo-checksums: generate-checksums for "
+                            dir "\n"))
+                  (generate-checksums dir ,%cargo-reference-project-file)))
+              (find-files "src/vendor" ".cargo-checksum.json"))))

Hmm, should return #t on success.
