// and see the AWS WAF Developer Guide (https://docs.aws.amazon.com/waf/latest/developerguide/waf-chapter.html)
// . With the latest version, AWS WAF has a single set of endpoints for regional
// and global use. Permanently deletes a Rule . You can't delete a Rule if it's
// still used in any WebACL objects or if it still includes any predicates, such
// as ByteMatchSet objects. If you just want to remove a Rule from a WebACL , use
// UpdateWebACL . To permanently delete a Rule from AWS WAF, perform the following
// steps:
//   - Update the Rule to remove predicates, if any. For more information, see
//     UpdateRule .
//   - Use GetChangeToken to get the change token that you provide in the
//     ChangeToken parameter of a DeleteRule request.
//   - Submit a DeleteRule request.
