Struct StepScalingPolicyConfiguration 

#[non_exhaustive]
pub struct StepScalingPolicyConfiguration {
    pub adjustment_type: Option<AdjustmentType>,
    pub step_adjustments: Option<Vec<StepAdjustment>>,
    pub min_adjustment_magnitude: Option<i32>,

Represents a step scaling policy configuration to use with Application Auto Scaling.

For more information, see Step scaling policies in the Application Auto Scaling User Guide.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

adjustment_type: Option<AdjustmentType>

Specifies how the ScalingAdjustment value in a StepAdjustment is interpreted (for example, an absolute number or a percentage). The valid values are ChangeInCapacity, ExactCapacity, and PercentChangeInCapacity.

AdjustmentType is required if you are adding a new step scaling policy configuration.

step_adjustments: Option<Vec<StepAdjustment>>

A set of adjustments that enable you to scale based on the size of the alarm breach.

At least one step adjustment is required if you are adding a new step scaling policy configuration.

min_adjustment_magnitude: Option<i32>

The minimum value to scale by when the adjustment type is PercentChangeInCapacity. For example, suppose that you create a step scaling policy to scale out an Amazon ECS service by 25 percent and you specify a MinAdjustmentMagnitude of 2. If the service has 4 tasks and the scaling policy is performed, 25 percent of 4 is 1. However, because you specified a MinAdjustmentMagnitude of 2, Application Auto Scaling scales out the service by 2 tasks.

cooldown: Option<i32>

The amount of time, in seconds, to wait for a previous scaling activity to take effect. If not specified, the default value is 300. For more information, see Cooldown period in the Application Auto Scaling User Guide.

metric_aggregation_type: Option<MetricAggregationType>

The aggregation type for the CloudWatch metrics. Valid values are Minimum, Maximum, and Average. If the aggregation type is null, the value is treated as Average.

Implementations

impl StepScalingPolicyConfiguration

pub fn adjustment_type(&self) -> Option<&AdjustmentType>

Specifies how the ScalingAdjustment value in a StepAdjustment is interpreted (for example, an absolute number or a percentage). The valid values are ChangeInCapacity, ExactCapacity, and PercentChangeInCapacity.

AdjustmentType is required if you are adding a new step scaling policy configuration.

pub fn step_adjustments(&self) -> &[StepAdjustment]

A set of adjustments that enable you to scale based on the size of the alarm breach.

At least one step adjustment is required if you are adding a new step scaling policy configuration.

If no value was sent for this field, a default will be set. If you want to determine if no value was sent, use .step_adjustments.is_none().

pub fn min_adjustment_magnitude(&self) -> Option<i32>

The minimum value to scale by when the adjustment type is PercentChangeInCapacity. For example, suppose that you create a step scaling policy to scale out an Amazon ECS service by 25 percent and you specify a MinAdjustmentMagnitude of 2. If the service has 4 tasks and the scaling policy is performed, 25 percent of 4 is 1. However, because you specified a MinAdjustmentMagnitude of 2, Application Auto Scaling scales out the service by 2 tasks.

pub fn cooldown(&self) -> Option<i32>

The amount of time, in seconds, to wait for a previous scaling activity to take effect. If not specified, the default value is 300. For more information, see Cooldown period in the Application Auto Scaling User Guide.

pub fn metric_aggregation_type(&self) -> Option<&MetricAggregationType>

The aggregation type for the CloudWatch metrics. Valid values are Minimum, Maximum, and Average. If the aggregation type is null, the value is treated as Average.

impl StepScalingPolicyConfiguration

pub fn builder() -> StepScalingPolicyConfigurationBuilder

Creates a new builder-style object to manufacture StepScalingPolicyConfiguration.

Trait Implementations

impl Clone for StepScalingPolicyConfiguration

fn clone(&self) -> StepScalingPolicyConfiguration

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for StepScalingPolicyConfiguration

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for StepScalingPolicyConfiguration

fn eq(&self, other: &StepScalingPolicyConfiguration) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
