| --- | |
| A callable value representing the type of a native or Starlark rule (created by | |
| [`rule()`](/versions/9.1.0/rules/lib/globals/bzl#rule)). Calling the value during | |
| evaluation of a package's BUILD file creates an instance of the rule and adds it to the | |
| package's target set. For more information, visit this page about | |
| [Rules](https://bazel.build/versions/9.1.0/extending/rules). |
