Struct SimpleScalingPolicyConfiguration 

pub struct SimpleScalingPolicyConfiguration {
    pub adjustment_type: Option<String>,
    pub cool_down: Option<i64>,
    pub scaling_adjustment: i64,
}

An automatic scaling configuration, which describes how the policy adds or removes instances, the cooldown period, and the number of EC2 instances that will be added each time the CloudWatch metric alarm condition is satisfied.

Fields

adjustment_type: Option<String>

The way in which EC2 instances are added (if ScalingAdjustment is a positive number) or terminated (if ScalingAdjustment is a negative number) each time the scaling activity is triggered. CHANGE_IN_CAPACITY is the default. CHANGE_IN_CAPACITY indicates that the EC2 instance count increments or decrements by ScalingAdjustment, which should be expressed as an integer. PERCENT_CHANGE_IN_CAPACITY indicates the instance count increments or decrements by the percentage specified by ScalingAdjustment, which should be expressed as an integer. For example, 20 indicates an increase in 20% increments of cluster capacity. EXACT_CAPACITY indicates the scaling activity results in an instance group with the number of EC2 instances specified by ScalingAdjustment, which should be expressed as a positive integer.

cool_down: Option<i64>

The amount of time, in seconds, after a scaling activity completes before any further trigger-related scaling activities can start. The default value is 0.

scaling_adjustment: i64

The amount by which to scale in or scale out, based on the specified AdjustmentType. A positive value adds to the instance group's EC2 instance count while a negative number removes instances. If AdjustmentType is set to EXACT_CAPACITY, the number should only be a positive integer. If AdjustmentType is set to PERCENT_CHANGE_IN_CAPACITY, the value should express the percentage as an integer. For example, -20 indicates a decrease in 20% increments of cluster capacity.

Trait Implementations

impl Clone for SimpleScalingPolicyConfiguration

fn clone(&self) -> SimpleScalingPolicyConfiguration

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SimpleScalingPolicyConfiguration

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

Formats the value using the given formatter.

impl Default for SimpleScalingPolicyConfiguration

fn default() -> SimpleScalingPolicyConfiguration

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for SimpleScalingPolicyConfiguration

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SimpleScalingPolicyConfiguration

fn eq(&self, other: &SimpleScalingPolicyConfiguration) -> 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.

impl Serialize for SimpleScalingPolicyConfiguration

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
