docs: // DescribeStackResources API operation for AWS CloudFormation.
  //
  // Returns AWS resource descriptions for running and deleted stacks. If StackName
  // is specified, all the associated resources that are part of the stack are
  // returned. If PhysicalResourceId is specified, the associated resources of
  // the stack that the resource belongs to are returned.
  //
  // Only the first 100 resources will be returned. If your stack has more resources
  // than this, you should use ListStackResources instead.
  //
  // For deleted stacks, DescribeStackResources returns resource information for
  // up to 90 days after the stack has been deleted.
  //
  // You must specify either StackName or PhysicalResourceId, but not both. In
  // addition, you can specify LogicalResourceId to filter the returned result.
  // For more information about resources, the LogicalResourceId and PhysicalResourceId,
  // go to the AWS CloudFormation User Guide (https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/).
  //
  // A ValidationError is returned if you specify both StackName and PhysicalResourceId
  // in the same request.
  //
  // 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 DescribeStackResources for usage and error information.
