Struct aws_sdk_emr::types::ScalingConstraints

#[non_exhaustive]
pub struct ScalingConstraints {
    pub min_capacity: Option<i32>,
    pub max_capacity: Option<i32>,
}

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

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.

min_capacity: Option<i32>

The lower boundary of Amazon EC2 instances in an instance group below which scaling activities are not allowed to shrink. Scale-in activities will not terminate instances below this boundary.

max_capacity: Option<i32>

The upper boundary of Amazon EC2 instances in an instance group beyond which scaling activities are not allowed to grow. Scale-out activities will not add instances beyond this boundary.

Implementations

impl ScalingConstraints

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

The lower boundary of Amazon EC2 instances in an instance group below which scaling activities are not allowed to shrink. Scale-in activities will not terminate instances below this boundary.

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

The upper boundary of Amazon EC2 instances in an instance group beyond which scaling activities are not allowed to grow. Scale-out activities will not add instances beyond this boundary.

impl ScalingConstraints

pub fn builder() -> ScalingConstraintsBuilder

Creates a new builder-style object to manufacture ScalingConstraints.

Trait Implementations

impl Clone for ScalingConstraints

fn clone(&self) -> ScalingConstraints

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ScalingConstraints

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

Formats the value using the given formatter.

impl PartialEq for ScalingConstraints

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