	//
	// Example:
	// my-cluster-snapshot1
	//
	// This member is required.
	SourceDBClusterSnapshotIdentifier *string

	// The identifier of the new cluster snapshot to create from the source cluster
	// snapshot. This parameter is not case sensitive. Constraints:
	//
	// * Must contain
	// from 1 to 63 letters, numbers, or hyphens.
	//
	// * The first character must be a
	// letter.
	//
	// * Cannot end with a hyphen or contain two consecutive

	// cluster snapshot, and otherwise false. The default is false.
	CopyTags *bool

	// The AWS KMS key ID for an encrypted cluster snapshot. The AWS KMS key ID is the
	// Amazon Resource Name (ARN), AWS KMS key identifier, or the AWS KMS key alias for
	// the AWS KMS encryption key. If you copy an encrypted cluster snapshot from your
	// AWS account, you can specify a value for KmsKeyId to encrypt the copy with a new
	// AWS KMS encryption key. If you don't specify a value for KmsKeyId, then the copy
	// of the cluster snapshot is encrypted with the same AWS KMS key as the source
	// cluster snapshot. If you copy an encrypted cluster snapshot that is shared from
	// another AWS account, then you must specify a value for KmsKeyId. To copy an
	// encrypted cluster snapshot to another AWS Region, set KmsKeyId to the AWS KMS
	// key ID that you want to use to encrypt the copy of the cluster snapshot in the
	// destination Region. AWS KMS encryption keys are specific to the AWS Region that
	// they are created in, and you can't use encryption keys from one AWS Region in
	// another AWS Region. If you copy an unencrypted cluster snapshot and specify a
	// value for the KmsKeyId parameter, an error is returned.
	KmsKeyId *string

	// The URL that contains a Signature Version 4 signed request for the
	// CopyDBClusterSnapshot API action in the AWS Region that contains the source
	// cluster snapshot to copy. You must use the PreSignedUrl parameter when copying a
	// cluster snapshot from another AWS Region. If you are using an AWS SDK tool or
	// the AWS CLI, you can specify SourceRegion (or --source-region for the AWS CLI)
	// instead of specifying PreSignedUrl manually. Specifying SourceRegion
	// autogenerates a pre-signed URL that is a valid request for the operation that
	// can be executed in the source AWS Region. The presigned URL must be a valid
	// request for the CopyDBClusterSnapshot API action that can be executed in the
	// source AWS Region that contains the cluster snapshot to be copied. The presigned
	// URL request must contain the following parameter values:
	//
	// * SourceRegion - The
	// ID of the region that contains the snapshot to be copied.
	//
	// *
	// SourceDBClusterSnapshotIdentifier - The identifier for the the encrypted cluster
	// snapshot to be copied. This identifier must be in the Amazon Resource Name (ARN)
	// format for the source AWS Region. For example, if you are copying an encrypted
	// cluster snapshot from the us-east-1 AWS Region, then your
	// SourceDBClusterSnapshotIdentifier looks something like the following:
	// arn:aws:rds:us-east-1:12345678012:sample-cluster:sample-cluster-snapshot.
	//
	// *
	// TargetDBClusterSnapshotIdentifier - The identifier for the new cluster snapshot
	// to be created. This parameter isn't case sensitive.
	PreSignedUrl *string

	// The AWS region the resource is in. The presigned URL will be created with this
	// region, if the PresignURL member is empty set.
	SourceRegion *string

	// The tags to be assigned to the cluster snapshot.

	// Used by the SDK's PresignURL autofill customization to specify the region the of
	// the client's request.
