docs: // DetectStackResourceDrift API operation for AWS CloudFormation.
  //
  // Returns information about whether a resource's actual configuration differs,
  // or has drifted, from it's expected configuration, as defined in the stack
  // template and any values specified as template parameters. This information
  // includes actual and expected property values for resources in which AWS CloudFormation
  // detects drift. Only resource properties explicitly defined in the stack template
  // are checked for drift. For more information about stack and resource drift,
  // see Detecting Unregulated Configuration Changes to Stacks and Resources (https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-stack-drift.html).
  //
  // Use DetectStackResourceDrift to detect drift on individual resources, or
  // DetectStackDrift to detect drift on all resources in a given stack that support
  // drift detection.
  //
  // Resources that do not currently support drift detection cannot be checked.
  // For a list of resources that support drift detection, see Resources that
  // Support Drift Detection (https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-stack-drift-resource-list.html).
  //
  // Returns awserr.Error for service API and SDK errors. Use runtime type assertions
  // with awserr.Error's Code and Message methods to get detailed information about
  // the error.
  //
  // See the AWS API reference guide for AWS CloudFormation's
  // API operation DetectStackResourceDrift for usage and error information.
