 attribute, and fail the build if not. It will also will compress the vendor
 directory into a tar.gz archive.
 
+The tarball with vendored dependencies contains a directory with the
+package's `name`, which is normally composed of `pname` and
+`version`. This means that the vendored dependencies hash
+(`cargoSha256`/`cargoHash`) is dependent on the package name and
+version. The `cargoDepsName` attribute can be used to use another name
+for the directory of vendored dependencies. For example, the hash can
+be made invariant to the version by setting `cargoDepsName` to
+`pname`:
+
+```nix
+rustPlatform.buildRustPackage rec {
+  pname = "broot";
+  version = "1.2.0";
+
+  src = fetchCrate {
