// Creates a new Capacity Reservation with the specified attributes. Capacity
// Reservations enable you to reserve capacity for your Amazon EC2 instances in a
// specific Availability Zone for any duration. This gives you the flexibility to
// selectively add capacity reservations and still get the Regional RI discounts
// for that usage. By creating Capacity Reservations, you ensure that you always
// have access to Amazon EC2 capacity when you need it, for as long as you need it.
// For more information, see Capacity Reservations (https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-capacity-reservations.html)
// in the Amazon EC2 User Guide. Your request to create a Capacity Reservation
// could fail if Amazon EC2 does not have sufficient capacity to fulfill the
// request. If your request fails due to Amazon EC2 capacity constraints, either
// try again at a later time, try in a different Availability Zone, or request a
// smaller capacity reservation. If your application is flexible across instance
// types and sizes, try to create a Capacity Reservation with different instance
// attributes. Your request could also fail if the requested quantity exceeds your
// On-Demand Instance limit for the selected instance type. If your request fails
// due to limit constraints, increase your On-Demand Instance limit for the
// required instance type and try again. For more information about increasing your
// instance limits, see Amazon EC2 Service Quotas (https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-resource-limits.html)
// in the Amazon EC2 User Guide.

// The ID of the Availability Zone in which to create the Capacity Reservation.
AvailabilityZoneId *string
// Unique, case-sensitive identifier that you provide to ensure the idempotency of
// the request. For more information, see Ensure Idempotency (https://docs.aws.amazon.com/AWSEC2/latest/APIReference/Run_Instance_Idempotency.html)
// .
ClientToken *string
// Checks whether you have the required permissions for the action, without
// actually making the request, and provides an error response. If you have the
// required permissions, the error response is DryRunOperation . Otherwise, it is
// UnauthorizedOperation .
DryRun *bool
// Indicates whether the Capacity Reservation supports EBS-optimized instances.
// This optimization provides dedicated throughput to Amazon EBS and an optimized
// configuration stack to provide optimal I/O performance. This optimization isn't
// available with all instance types. Additional usage charges apply when using an
// EBS- optimized instance.
EbsOptimized *bool
// The date and time at which the Capacity Reservation expires. When a Capacity
// Reservation expires, the reserved capacity is released and you can no longer
// launch instances into it. The Capacity Reservation's state changes to expired
// when it reaches its end date and time. You must provide an EndDate value if
// EndDateType is limited . Omit EndDate if EndDateType is unlimited . If the
// EndDateType is limited , the Capacity Reservation is cancelled within an hour
// from the specified time. For example, if you specify 5/31/2019, 13:30:55, the
// Capacity Reservation is guaranteed to end between 13:30:55 and 14:30:55 on
// 5/31/2019.
EndDate *time.Time
// Indicates the way in which the Capacity Reservation ends. A Capacity
// Reservation can have one of the following end types:
// - unlimited - The Capacity Reservation remains active until you explicitly
// cancel it. Do not provide an EndDate if the EndDateType is unlimited .
// - limited - The Capacity Reservation expires automatically at a specified date
// and time. You must provide an EndDate value if the EndDateType value is
// limited .
EndDateType types.EndDateType
// Deprecated.
EphemeralStorage *bool
// Indicates the type of instance launches that the Capacity Reservation accepts.
// The options include:
// - open - The Capacity Reservation automatically matches all instances that
// have matching attributes (instance type, platform, and Availability Zone).
// Instances that have matching attributes run in the Capacity Reservation
// automatically without specifying any additional parameters.
// - targeted - The Capacity Reservation only accepts instances that have
// matching attributes (instance type, platform, and Availability Zone), and
// explicitly target the Capacity Reservation. This ensures that only permitted
// instances can use the reserved capacity.
// Default: open
InstanceMatchCriteria types.InstanceMatchCriteria
// The Amazon Resource Name (ARN) of the Outpost on which to create the Capacity
// Reservation.
OutpostArn *string
// The Amazon Resource Name (ARN) of the cluster placement group in which to
// create the Capacity Reservation. For more information, see Capacity
// Reservations for cluster placement groups (https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/cr-cpg.html)
// in the Amazon EC2 User Guide.
PlacementGroupArn *string
// The tags to apply to the Capacity Reservation during launch.
TagSpecifications []types.TagSpecification
// Indicates the tenancy of the Capacity Reservation. A Capacity Reservation can
// have one of the following tenancy settings:
// - default - The Capacity Reservation is created on hardware that is shared
// with other Amazon Web Services accounts.
// - dedicated - The Capacity Reservation is created on single-tenant hardware
// that is dedicated to a single Amazon Web Services account.
