Struct aws_sdk_emr::types::PlacementGroupConfig

#[non_exhaustive]
pub struct PlacementGroupConfig {
    pub instance_role: Option<InstanceRoleType>,
    pub placement_strategy: Option<PlacementGroupStrategy>,
}

Placement group configuration for an Amazon EMR cluster. The configuration specifies the placement strategy that can be applied to instance roles during cluster creation.

To use this configuration, consider attaching managed policy AmazonElasticMapReducePlacementGroupPolicy to the Amazon EMR role.

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.

instance_role: Option<InstanceRoleType>

Role of the instance in the cluster.

Starting with Amazon EMR release 5.23.0, the only supported instance role is MASTER.

placement_strategy: Option<PlacementGroupStrategy>

Amazon EC2 Placement Group strategy associated with instance role.

Starting with Amazon EMR release 5.23.0, the only supported placement strategy is SPREAD for the MASTER instance role.

Implementations

impl PlacementGroupConfig

pub fn instance_role(&self) -> Option<&InstanceRoleType>

Role of the instance in the cluster.

Starting with Amazon EMR release 5.23.0, the only supported instance role is MASTER.

pub fn placement_strategy(&self) -> Option<&PlacementGroupStrategy>

Amazon EC2 Placement Group strategy associated with instance role.

Starting with Amazon EMR release 5.23.0, the only supported placement strategy is SPREAD for the MASTER instance role.

impl PlacementGroupConfig

pub fn builder() -> PlacementGroupConfigBuilder

Creates a new builder-style object to manufacture PlacementGroupConfig.

Trait Implementations

impl Clone for PlacementGroupConfig

fn clone(&self) -> PlacementGroupConfig

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PlacementGroupConfig

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

Formats the value using the given formatter.

impl PartialEq for PlacementGroupConfig

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