Struct aws_sdk_emr::model::AutoScalingPolicy

#[non_exhaustive]
pub struct AutoScalingPolicy { /* private fields */ }

An automatic scaling policy for a core instance group or task instance group in an Amazon EMR cluster. An automatic scaling policy defines how an instance group dynamically adds and terminates EC2 instances in response to the value of a CloudWatch metric. See PutAutoScalingPolicy.

Implementations

impl AutoScalingPolicy

pub fn constraints(&self) -> Option<&ScalingConstraints>

The upper and lower EC2 instance limits for an automatic scaling policy. Automatic scaling activity will not cause an instance group to grow above or below these limits.

pub fn rules(&self) -> Option<&[ScalingRule]>

The scale-in and scale-out rules that comprise the automatic scaling policy.

impl AutoScalingPolicy

pub fn builder() -> Builder

Creates a new builder-style object to manufacture AutoScalingPolicy.

Trait Implementations

impl Clone for AutoScalingPolicy

fn clone(&self) -> AutoScalingPolicy

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AutoScalingPolicy

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

Formats the value using the given formatter.

impl PartialEq<AutoScalingPolicy> for AutoScalingPolicy

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