Struct CapacityReservationOptions

#[non_exhaustive]
pub struct CapacityReservationOptions {
    pub usage_strategy: Option<FleetCapacityReservationUsageStrategy>,
}

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

This strategy can only be used if the EC2 Fleet is of type instant.

For more information about Capacity Reservations, see On-Demand Capacity Reservations in the Amazon EC2 User Guide. For examples of using Capacity Reservations in an EC2 Fleet, see EC2 Fleet example configurations in the Amazon EC2 User Guide.

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.

usage_strategy: Option<FleetCapacityReservationUsageStrategy>

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 or prioritized) 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 or prioritized).

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

Implementations

impl CapacityReservationOptions

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

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 or prioritized) 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 or prioritized).

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

impl CapacityReservationOptions

pub fn builder() -> CapacityReservationOptionsBuilder

Creates a new builder-style object to manufacture CapacityReservationOptions.

Trait Implementations

impl Clone for CapacityReservationOptions

fn clone(&self) -> CapacityReservationOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CapacityReservationOptions

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

Formats the value using the given formatter.

impl PartialEq for CapacityReservationOptions

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

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

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

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