Struct aws_sdk_ec2::types::TargetCapacitySpecification

#[non_exhaustive]
pub struct TargetCapacitySpecification {
    pub total_target_capacity: Option<i32>,
    pub on_demand_target_capacity: Option<i32>,
    pub spot_target_capacity: Option<i32>,
    pub default_target_capacity_type: Option<DefaultTargetCapacityType>,
    pub target_capacity_unit_type: Option<TargetCapacityUnitType>,
}

The number of units to request. You can choose to set the target capacity in terms of instances or a performance characteristic that is important to your application workload, such as vCPUs, memory, or I/O. If the request type is maintain, you can specify a target capacity of 0 and add capacity later.

You can use the On-Demand Instance MaxTotalPrice parameter, the Spot Instance MaxTotalPrice, or both to ensure that your fleet cost does not exceed your budget. If you set a maximum price per hour for the On-Demand Instances and Spot Instances in your request, EC2 Fleet will launch instances until it reaches the maximum amount that you're willing to pay. When the maximum amount you're willing to pay is reached, the fleet stops launching instances even if it hasn’t met the target capacity. The MaxTotalPrice parameters are located in OnDemandOptions and SpotOptions.

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.

total_target_capacity: Option<i32>

The number of units to request, filled using DefaultTargetCapacityType.

on_demand_target_capacity: Option<i32>

The number of On-Demand units to request. If you specify a target capacity for Spot units, you cannot specify a target capacity for On-Demand units.

spot_target_capacity: Option<i32>

The maximum number of Spot units to launch. If you specify a target capacity for On-Demand units, you cannot specify a target capacity for Spot units.

default_target_capacity_type: Option<DefaultTargetCapacityType>

The default TotalTargetCapacity, which is either Spot or On-Demand.

target_capacity_unit_type: Option<TargetCapacityUnitType>

The unit for the target capacity. TargetCapacityUnitType can only be specified when InstanceRequirements is specified.

Default: units (translates to number of instances)

Implementations

impl TargetCapacitySpecification

pub fn total_target_capacity(&self) -> Option<i32>

The number of units to request, filled using DefaultTargetCapacityType.

pub fn on_demand_target_capacity(&self) -> Option<i32>

The number of On-Demand units to request. If you specify a target capacity for Spot units, you cannot specify a target capacity for On-Demand units.

pub fn spot_target_capacity(&self) -> Option<i32>

The maximum number of Spot units to launch. If you specify a target capacity for On-Demand units, you cannot specify a target capacity for Spot units.

pub fn default_target_capacity_type(&self) -> Option<&DefaultTargetCapacityType>

The default TotalTargetCapacity, which is either Spot or On-Demand.

pub fn target_capacity_unit_type(&self) -> Option<&TargetCapacityUnitType>

The unit for the target capacity. TargetCapacityUnitType can only be specified when InstanceRequirements is specified.

Default: units (translates to number of instances)

impl TargetCapacitySpecification

pub fn builder() -> TargetCapacitySpecificationBuilder

Creates a new builder-style object to manufacture TargetCapacitySpecification.

Trait Implementations

impl Clone for TargetCapacitySpecification

fn clone(&self) -> TargetCapacitySpecification

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TargetCapacitySpecification

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

Formats the value using the given formatter.

impl PartialEq<TargetCapacitySpecification> for TargetCapacitySpecification

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