Struct aws_sdk_emr::model::OnDemandCapacityReservationOptions

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

Describes the strategy for using unused Capacity Reservations for fulfilling On-Demand capacity.

Implementations

impl OnDemandCapacityReservationOptions

pub fn usage_strategy(
    &self
) -> Option<&OnDemandCapacityReservationUsageStrategy>

Indicates whether to use unused Capacity Reservations for fulfilling On-Demand capacity.

If you specify use-capacity-reservations-first, the fleet uses unused Capacity Reservations to fulfill On-Demand capacity up to the target On-Demand capacity. If multiple instance pools have unused Capacity Reservations, the On-Demand allocation strategy (lowest-price) is applied. If the number of unused Capacity Reservations is less than the On-Demand target capacity, the remaining On-Demand target capacity is launched according to the On-Demand allocation strategy (lowest-price).

If you do not specify a value, the fleet fulfills the On-Demand capacity according to the chosen On-Demand allocation strategy.

pub fn capacity_reservation_preference(
    &self
) -> Option<&OnDemandCapacityReservationPreference>

Indicates the instance's Capacity Reservation preferences. Possible preferences include:

• open - The instance can run in any open Capacity Reservation that has matching attributes (instance type, platform, Availability Zone).

• none - The instance avoids running in a Capacity Reservation even if one is available. The instance runs as an On-Demand Instance.

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

The ARN of the Capacity Reservation resource group in which to run the instance.

impl OnDemandCapacityReservationOptions

pub fn builder() -> Builder

Creates a new builder-style object to manufacture OnDemandCapacityReservationOptions.

Trait Implementations

impl Clone for OnDemandCapacityReservationOptions

fn clone(&self) -> OnDemandCapacityReservationOptions

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OnDemandCapacityReservationOptions

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

Formats the value using the given formatter.

impl PartialEq<OnDemandCapacityReservationOptions> for OnDemandCapacityReservationOptions

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