// Creates a Network File System (NFS) file share on an existing S3 File Gateway.
// In Storage Gateway, a file share is a file system mount point backed by Amazon
// S3 cloud storage. Storage Gateway exposes file shares using an NFS interface.
// This operation is only supported for S3 File Gateways. S3 File gateway requires
// Security Token Service (Amazon Web Services STS) to be activated to enable you
// to create a file share. Make sure Amazon Web Services STS is activated in the
// Amazon Web Services Region you are creating your S3 File Gateway in. If Amazon
// Web Services STS is not activated in the Amazon Web Services Region, activate
// it. For information about how to activate Amazon Web Services STS, see
// Activating and deactivating Amazon Web Services STS in an Amazon Web Services
// Region (https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_enable-regions.html)
// in the Identity and Access Management User Guide. S3 File Gateways do not
// support creating hard or symbolic links on a file share.

	GatewayARN *string

	// A custom ARN for the backend storage used for storing data for file shares. It

	// access point ARN or access point alias, as shown in the following examples.

	// arn:aws:s3:region:account-id:accesspoint/access-point-name/prefix/ If you

	// Gateway assumes when it accesses the underlying storage.
	//
	// This member is required.
	Role *string

	// The Amazon Resource Name (ARN) of the storage used for audit logs.
	AuditDestinationARN *string

	// Specifies the Region of the S3 bucket where the NFS file share stores files.
	// This parameter is required for NFS file shares that connect to Amazon S3 through
	// a VPC endpoint, a VPC access point, or an access point alias that points to a
	// VPC access point.
	BucketRegion *string

	// Specifies refresh cache information for the file share.

	// must contain either valid IP addresses or valid CIDR blocks.

	// The default storage class for objects put into an Amazon S3 bucket by the S3
	// File Gateway. The default value is S3_STANDARD . Optional. Valid Values:
	// S3_STANDARD | S3_INTELLIGENT_TIERING | S3_STANDARD_IA | S3_ONEZONE_IA
	DefaultStorageClass *string

	// The name of the file share. Optional. FileShareName must be set if an S3 prefix
	// name is set in LocationARN , or if an access point or access point alias is used.
	FileShareName *string

	// A value that enables guessing of the MIME type for uploaded objects based on
	// file extensions. Set this value to true to enable MIME type guessing, otherwise

	NFSFileShareDefaults *types.NFSFileShareDefaults

	// The notification policy of the file share. SettlingTimeInSeconds controls the
	// number of seconds to wait after the last point in time a client wrote to a file
	// before generating an ObjectUploaded notification. Because clients can make many
	// small writes to files, it's best to set this parameter for as long as possible
	// to avoid generating multiple notifications for the same file in a small time
	// period. SettlingTimeInSeconds has no effect on the timing of the object
	// uploading to Amazon S3, only the timing of the notification. The following
	// example sets NotificationPolicy on with SettlingTimeInSeconds set to 60.
	// {"Upload": {"SettlingTimeInSeconds": 60}} The following example sets
	// NotificationPolicy off. {}

	// A value that sets who pays the cost of the request and the cost associated with
	// data download from the S3 bucket. If this value is set to true , the requester
	// pays the costs; otherwise, the S3 bucket owner pays. However, the S3 bucket
	// owner always pays the cost of storing data. RequesterPays is a configuration
	// for the S3 bucket that backs the file share, so make sure that the configuration
	// on the file share is the same as the S3 bucket configuration. Valid Values: true
	// | false
	RequesterPays *bool

	// A value that maps a user to anonymous user. Valid values are the following:
	//   - RootSquash : Only root is mapped to anonymous user.
	//   - NoSquash : No one is mapped to anonymous user.
