Struct aws_sdk_emr::types::PlacementType

#[non_exhaustive]
pub struct PlacementType {
    pub availability_zone: Option<String>,
    pub availability_zones: Option<Vec<String>>,
}

The Amazon EC2 Availability Zone configuration of the cluster (job flow).

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.

availability_zone: Option<String>

The Amazon EC2 Availability Zone for the cluster. AvailabilityZone is used for uniform instance groups, while AvailabilityZones (plural) is used for instance fleets.

availability_zones: Option<Vec<String>>

When multiple Availability Zones are specified, Amazon EMR evaluates them and launches instances in the optimal Availability Zone. AvailabilityZones is used for instance fleets, while AvailabilityZone (singular) is used for uniform instance groups.

The instance fleet configuration is available only in Amazon EMR releases 4.8.0 and later, excluding 5.0.x versions.

Implementations

impl PlacementType

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

The Amazon EC2 Availability Zone for the cluster. AvailabilityZone is used for uniform instance groups, while AvailabilityZones (plural) is used for instance fleets.

pub fn availability_zones(&self) -> &[String]

When multiple Availability Zones are specified, Amazon EMR evaluates them and launches instances in the optimal Availability Zone. AvailabilityZones is used for instance fleets, while AvailabilityZone (singular) is used for uniform instance groups.

The instance fleet configuration is available only in Amazon EMR releases 4.8.0 and later, excluding 5.0.x versions.

If no value was sent for this field, a default will be set. If you want to determine if no value was sent, use .availability_zones.is_none().

impl PlacementType

pub fn builder() -> PlacementTypeBuilder

Creates a new builder-style object to manufacture PlacementType.

Trait Implementations

impl Clone for PlacementType

fn clone(&self) -> PlacementType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PlacementType

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

Formats the value using the given formatter.

impl PartialEq for PlacementType

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