// a scalable target, you can use this operation to update the minimum and maximum
// values for your scalable dimension.
//
// After you register a scalable target, you can create and apply scaling policies
// using PutScalingPolicy. You can view the scaling policies for a service namespace
// using DescribeScalableTargets. If you are no longer using a scalable target,
// you can deregister it using DeregisterScalableTarget.

// Returns awserr.Error for service API and SDK errors. Use runtime type assertions

// See the AWS API reference guide for Application Auto Scaling's
// API operation RegisterScalableTarget for usage and error information.
//
// Returned Error Codes:
//   * ValidationException
//   An exception was thrown for a validation issue. Review the available parameters

//   * LimitExceededException
//   Your account exceeded a limit. This exception is thrown when a per-account

// Represents a step adjustment for a StepScalingPolicyConfiguration. Describes

// For the following examples, suppose that you have an alarm with a breach
// threshold of 50:
//
//    * To trigger the adjustment when the metric is greater than or equal to
//    50 and less than 60, specify a lower bound of 0 and an upper bound of
//    10.
//
//    * To trigger the adjustment when the metric is greater than 40 and less
//    than or equal to 50, specify a lower bound of -10 and an upper bound of
//    0.
//
// There are a few rules for the step adjustments for your step policy:
//
//    * The ranges of your step adjustments can't overlap or have a gap.
//
//    * At most one step adjustment can have a null lower bound. If one step
//    adjustment has a negative lower bound, then there must be a step adjustment
//    with a null lower bound.
//
//    * At most one step adjustment can have a null upper bound. If one step
//    adjustment has a positive upper bound, then there must be a step adjustment
//    with a null upper bound.
//
//    * The upper and lower bound can't be null in the same step adjustment.
