    #   requests][1].
    #
    #   The `PresignedUrl` should use the snapshot source endpoint, the
    #   `CopySnapshot` action, and include the `SourceRegion`,
    #   `SourceSnapshotId`, and `DestinationRegion` parameters. The
    #   `PresignedUrl` must be signed using Amazon Web Services Signature
    #   Version 4. Because EBS snapshots are stored in Amazon S3, the
    #   signing algorithm for this parameter uses the same logic that is
    #   described in [Authenticating Requests: Using Query Parameters
    #   (Amazon Web Services Signature Version 4)][2] in the *Amazon Simple
    #   Storage Service API Reference*. An invalid or improperly signed
    #   `PresignedUrl` will cause the copy operation to fail asynchronously,
    #   and the snapshot will move to an `error` state.

    #   if the instance that this ENI will be attached to relies on its IPv6
    #   address not changing. Amazon Web Services will automatically assign
    #   an IPv6 address associated with the ENI attached to your instance to
    #   be the primary IPv6 address. Once you enable an IPv6 GUA address to
    #   be a primary IPv6, you cannot disable it. When you enable an IPv6
    #   GUA address to be a primary IPv6, the first IPv6 GUA will be made
    #   the primary IPv6 address until the instance is terminated or the
    #   network interface is detached. If you have multiple IPv6 addresses
    #   associated with an ENI attached to your instance and you enable a

    #   * `owner-id` - The ID of the Amazon Web Services account that owns
    #     the Capacity Reservation.
    #
    #   * `instance-platform` - The type of operating system for which the
    #     Capacity Reservation reserves capacity.
    #
    #   * `availability-zone` - The Availability Zone of the Capacity
    #     Reservation.
    #
    #   * `tenancy` - 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.
    #
    #   * `outpost-arn` - The Amazon Resource Name (ARN) of the Outpost on
    #     which the Capacity Reservation was created.
    #
    #   * `state` - The current state of the Capacity Reservation. A
    #     Capacity Reservation can be in one of the following states:
    #
    #     * `active`- The Capacity Reservation is active and the capacity is
    #       available for your use.
    #
    #     * `expired` - The Capacity Reservation expired automatically at
    #       the date and time specified in your request. The reserved
    #       capacity is no longer available for your use.
    #
    #     * `cancelled` - The Capacity Reservation was cancelled. The
    #       reserved capacity is no longer available for your use.
    #
    #     * `pending` - The Capacity Reservation request was successful but
    #       the capacity provisioning is still pending.
    #
    #     * `failed` - The Capacity Reservation request has failed. A
    #       request might fail due to invalid request parameters, capacity
    #       constraints, or instance limit constraints. Failed requests are
    #       retained for 60 minutes.
    #
    #   * `start-date` - The date and time at which the Capacity Reservation
    #     was started.
    #
    #   * `end-date` - 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.
    #
    #   * `end-date-type` - 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.
    #
    #     * `limited` - The Capacity Reservation expires automatically at a
    #       specified date and time.
    #
    #   * `instance-match-criteria` - Indicates the type of instance
    #     launches that the Capacity Reservation accepts. The options
    #     include:
    #
    #     * `open` - The Capacity Reservation accepts all instances that
    #       have matching attributes (instance type, platform, and
    #       Availability Zone). Instances that have matching attributes
    #       launch into 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.
    #
    #   * `placement-group-arn` - The ARN of the cluster placement group in
    #     which the Capacity Reservation was created.

    # @!attribute [rw] encrypted
    #   Indicates whether the encryption state of an EBS volume is changed
    #   while being restored from a backing snapshot. The effect of setting
    #   the encryption state to `true` depends on the volume origin (new or
    #   from a snapshot), starting encryption state, ownership, and whether
    #   encryption by default is enabled. For more information, see [Amazon
    #   EBS encryption][1] in the *Amazon EC2 User Guide*.
    #
    #   In no case can you remove encryption from an encrypted volume.
    #
    #   Encrypted volumes can only be attached to instances that support
    #   Amazon EBS encryption. For more information, see [Supported instance
    #   types][2].
    #
    #   This parameter is not returned by DescribeImageAttribute.
    #
    #   For CreateImage and RegisterImage, whether you can include this
    #   parameter, and the allowed values differ depending on the type of
    #   block device mapping you are creating.
    #
    #   * If you are creating a block device mapping for a **new (empty)
    #     volume**, you can include this parameter, and specify either
    #     `true` for an encrypted volume, or `false` for an unencrypted
    #     volume. If you omit this parameter, it defaults to `false`
    #     (unencrypted).
    #
    #   * If you are creating a block device mapping from an **existing
    #     encrypted or unencrypted snapshot**, you must omit this parameter.
    #     If you include this parameter, the request will fail, regardless
    #     of the value that you specify.
    #
    #   * If you are creating a block device mapping from an **existing
    #     unencrypted volume**, you can include this parameter, but you must
    #     specify `false`. If you specify `true`, the request will fail. In
    #     this case, we recommend that you omit the parameter.
    #
    #   * If you are creating a block device mapping from an **existing
    #     encrypted volume**, you can include this parameter, and specify
    #     either `true` or `false`. However, if you specify `false`, the
    #     parameter is ignored and the block device mapping is always
    #     encrypted. In this case, we recommend that you omit the parameter.

    #   @return [String]
    #
    # @!attribute [rw] event_sub_type
    #   The event.
    #
    #   `error` events:
    #
    #   * `iamFleetRoleInvalid` - The EC2 Fleet or Spot Fleet does not have
    #     the required permissions either to launch or terminate an
    #     instance.
    #
    #   * `allLaunchSpecsTemporarilyBlacklisted` - None of the
    #     configurations are valid, and several attempts to launch instances
    #     have failed. For more information, see the description of the
    #     event.
    #
    #   * `spotInstanceCountLimitExceeded` - You've reached the limit on
    #     the number of Spot Instances that you can launch.
    #
    #   * `spotFleetRequestConfigurationInvalid` - The configuration is not
    #     valid. For more information, see the description of the event.
    #
    #   `fleetRequestChange` events:
    #
    #   * `active` - The EC2 Fleet or Spot Fleet request has been validated
    #     and Amazon EC2 is attempting to maintain the target number of
    #     running instances.
    #
    #   * `deleted` (EC2 Fleet) / `cancelled` (Spot Fleet) - The EC2 Fleet
    #     is deleted or the Spot Fleet request is canceled and has no
    #     running instances. The EC2 Fleet or Spot Fleet will be deleted two
    #     days after its instances are terminated.
    #
    #   * `deleted_running` (EC2 Fleet) / `cancelled_running` (Spot Fleet) -
    #     The EC2 Fleet is deleted or the Spot Fleet request is canceled and
    #     does not launch additional instances. Its existing instances
    #     continue to run until they are interrupted or terminated. The
    #     request remains in this state until all instances are interrupted
    #     or terminated.
    #
    #   * `deleted_terminating` (EC2 Fleet) / `cancelled_terminating` (Spot
    #     Fleet) - The EC2 Fleet is deleted or the Spot Fleet request is
    #     canceled and its instances are terminating. The request remains in
    #     this state until all instances are terminated.
    #
    #   * `expired` - The EC2 Fleet or Spot Fleet request has expired. If
    #     the request was created with `TerminateInstancesWithExpiration`
    #     set, a subsequent `terminated` event indicates that the instances
    #     are terminated.
    #
    #   * `modify_in_progress` - The EC2 Fleet or Spot Fleet request is
    #     being modified. The request remains in this state until the
    #     modification is fully processed.
    #
    #   * `modify_succeeded` - The EC2 Fleet or Spot Fleet request was
    #     modified.
    #
    #   * `submitted` - The EC2 Fleet or Spot Fleet request is being
    #     evaluated and Amazon EC2 is preparing to launch the target number
    #     of instances.
    #
    #   * `progress` - The EC2 Fleet or Spot Fleet request is in the process
    #     of being fulfilled.
    #
    #   `instanceChange` events:
    #
    #   * `launched` - A new instance was launched.
    #
    #   * `terminated` - An instance was terminated by the user.
    #
    #   * `termination_notified` - An instance termination notification was
    #     sent when a Spot Instance was terminated by Amazon EC2 during
    #     scale-down, when the target capacity of the fleet was modified
    #     down, for example, from a target capacity of 4 to a target
    #     capacity of 3.
    #
    #   `Information` events:
    #
    #   * `fleetProgressHalted` - The price in every launch specification is
    #     not valid because it is below the Spot price (all the launch
    #     specifications have produced `launchSpecUnusable` events). A
    #     launch specification might become valid if the Spot price changes.
    #
    #   * `launchSpecTemporarilyBlacklisted` - The configuration is not
    #     valid and several attempts to launch instances have failed. For
    #     more information, see the description of the event.
    #
    #   * `launchSpecUnusable` - The price in a launch specification is not
    #     valid because it is below the Spot price.
    #
    #   * `registerWithLoadBalancersFailed` - An attempt to register
    #     instances with load balancers failed. For more information, see
    #     the description of the event.

    #   An identifier for the symmetric KMS key to use when creating the

    #   non-default KMS key; if this parameter is not specified, the default
    #   KMS key for EBS is used. If a `KmsKeyId` is specified, the
    #   `Encrypted` flag must also be set.
    #
    #   The KMS key identifier may be provided in any of the following
    #   formats:
    #
    #   * Key ID
    #
    #   * Key alias
    #
    #   * ARN using key ID. The ID ARN contains the `arn:aws:kms` namespace,
    #     followed by the Region of the key, the Amazon Web Services account
    #     ID of the key owner, the `key` namespace, and then the key ID. For
    #     example,
    #     arn:aws:kms:*us-east-1*:*012345678910*:key/*abcd1234-a123-456a-a12b-a123b4cd56ef*.
    #
    #   * ARN using key alias. The alias ARN contains the `arn:aws:kms`
    #     namespace, followed by the Region of the key, the Amazon Web
    #     Services account ID of the key owner, the `alias` namespace, and
    #     then the key alias. For example,
    #     arn:aws:kms:*us-east-1*:*012345678910*:alias/*ExampleAlias*.
    #
    #   Amazon Web Services parses `KmsKeyId` asynchronously, meaning that
    #   the action you call may appear to complete even though you provided
    #   an invalid identifier. This action will eventually report failure.
    #
    #   The specified KMS key must exist in the Region that the AMI is being
    #   copied to.
    #
    #   Amazon EBS does not support asymmetric KMS keys.
    #   @return [String]
    #
    # @!attribute [rw] license_type
    #   The license type to be used for the Amazon Machine Image (AMI) after
    #   importing.
    #
    #   Specify `AWS` to replace the source-system license with an Amazon
    #   Web Services license or `BYOL` to retain the source-system license.
    #   Leaving this parameter undefined is the same as choosing `AWS` when
    #   importing a Windows Server operating system, and the same as
    #   choosing `BYOL` when importing a Windows client operating system
    #   (such as Windows 10) or a Linux operating system.
    #
    #   To use `BYOL`, you must have existing licenses with rights to use
    #   these licenses in a third party cloud, such as Amazon Web Services.

    #   An identifier for the symmetric KMS key to use when creating the

    #     ID of the key owner, the `key` namespace, and then the key ID. For

    #
    #   * ARN using key alias. The alias ARN contains the `arn:aws:kms`
    #     namespace, followed by the Region of the key, the Amazon Web
    #     Services account ID of the key owner, the `alias` namespace, and
    #     then the key alias. For example,
    #     arn:aws:kms:*us-east-1*:*012345678910*:alias/*ExampleAlias*.

    #   Amazon Web Services parses `KmsKeyId` asynchronously, meaning that
    #   the action you call may appear to complete even though you provided
    #   an invalid identifier. This action will eventually report failure.
