pub struct SimpleScalingPolicyConfigurationBuilder { /* private fields */ }

A builder for SimpleScalingPolicyConfiguration.

Implementations

impl SimpleScalingPolicyConfigurationBuilder

pub fn adjustment_type(self, input: AdjustmentType) -> Self

The way in which Amazon 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 Amazon 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 Amazon EC2 instances specified by ScalingAdjustment, which should be expressed as a positive integer.

pub fn set_adjustment_type(self, input: Option<AdjustmentType>) -> Self

The way in which Amazon 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 Amazon 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 Amazon EC2 instances specified by ScalingAdjustment, which should be expressed as a positive integer.

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

The way in which Amazon 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 Amazon 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 Amazon EC2 instances specified by ScalingAdjustment, which should be expressed as a positive integer.

pub fn scaling_adjustment(self, input: i32) -> Self

The amount by which to scale in or scale out, based on the specified AdjustmentType. A positive value adds to the instance group's Amazon 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.

This field is required.

pub fn set_scaling_adjustment(self, input: Option<i32>) -> Self

The amount by which to scale in or scale out, based on the specified AdjustmentType. A positive value adds to the instance group's Amazon 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.

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

The amount by which to scale in or scale out, based on the specified AdjustmentType. A positive value adds to the instance group's Amazon 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.

pub fn cool_down(self, input: i32) -> Self

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.

pub fn set_cool_down(self, input: Option<i32>) -> Self

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.

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

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.

pub fn build(self) -> SimpleScalingPolicyConfiguration

Consumes the builder and constructs a SimpleScalingPolicyConfiguration.

Trait Implementations

impl Clone for SimpleScalingPolicyConfigurationBuilder

fn clone(&self) -> SimpleScalingPolicyConfigurationBuilder

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SimpleScalingPolicyConfigurationBuilder

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

Formats the value using the given formatter.

impl Default for SimpleScalingPolicyConfigurationBuilder

fn default() -> SimpleScalingPolicyConfigurationBuilder

Returns the “default value” for a type.

impl PartialEq for SimpleScalingPolicyConfigurationBuilder

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

This method tests for self and other values to be equal, and is used by ==.

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

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