Struct MetricDimension

#[non_exhaustive]
pub struct MetricDimension {
    pub key: Option<String>,
    pub value: Option<String>,
}

A CloudWatch dimension, which is specified using a Key (known as a Name in CloudWatch), Value pair. By default, Amazon EMR uses one dimension whose Key is JobFlowID and Value is a variable representing the cluster ID, which is ${emr.clusterId}. This enables the rule to bootstrap when the cluster ID becomes available.

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.

key: Option<String>

The dimension name.

value: Option<String>

The dimension value.

Implementations

impl MetricDimension

pub fn key(&self) -> Option<&str>

The dimension name.

pub fn value(&self) -> Option<&str>

The dimension value.

impl MetricDimension

pub fn builder() -> MetricDimensionBuilder

Creates a new builder-style object to manufacture MetricDimension.

Trait Implementations

impl Clone for MetricDimension

fn clone(&self) -> MetricDimension

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MetricDimension

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

Formats the value using the given formatter.

impl PartialEq for MetricDimension

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

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

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

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