Enum aws_sdk_fsx::types::AdministrativeActionType

#[non_exhaustive]
pub enum AdministrativeActionType {
    FileSystemAliasAssociation,
    FileSystemAliasDisassociation,
    FileSystemUpdate,
    ReleaseNfsV3Locks,
    SnapshotUpdate,
    StorageOptimization,
    VolumeRestore,
    VolumeUpdate,
    Unknown(UnknownVariantValue),
}

When writing a match expression against AdministrativeActionType, it is important to ensure your code is forward-compatible. That is, if a match arm handles a case for a feature that is supported by the service but has not been represented as an enum variant in a current version of SDK, your code should continue to work when you upgrade SDK to a future version in which the enum does include a variant for that feature.

Here is an example of how you can make a match expression forward-compatible:

# let administrativeactiontype = unimplemented!();
match administrativeactiontype {
    AdministrativeActionType::FileSystemAliasAssociation => { /* ... */ },
    AdministrativeActionType::FileSystemAliasDisassociation => { /* ... */ },
    AdministrativeActionType::FileSystemUpdate => { /* ... */ },
    AdministrativeActionType::ReleaseNfsV3Locks => { /* ... */ },
    AdministrativeActionType::SnapshotUpdate => { /* ... */ },
    AdministrativeActionType::StorageOptimization => { /* ... */ },
    AdministrativeActionType::VolumeRestore => { /* ... */ },
    AdministrativeActionType::VolumeUpdate => { /* ... */ },
    other @ _ if other.as_str() == "NewFeature" => { /* handles a case for `NewFeature` */ },
    _ => { /* ... */ },
}

The above code demonstrates that when administrativeactiontype represents NewFeature, the execution path will lead to the second last match arm, even though the enum does not contain a variant AdministrativeActionType::NewFeature in the current version of SDK. The reason is that the variable other, created by the @ operator, is bound to AdministrativeActionType::Unknown(UnknownVariantValue("NewFeature".to_owned())) and calling as_str on it yields "NewFeature". This match expression is forward-compatible when executed with a newer version of SDK where the variant AdministrativeActionType::NewFeature is defined. Specifically, when administrativeactiontype represents NewFeature, the execution path will hit the second last match arm as before by virtue of calling as_str on AdministrativeActionType::NewFeature also yielding "NewFeature".

Explicitly matching on the Unknown variant should be avoided for two reasons:

• The inner data UnknownVariantValue is opaque, and no further information can be extracted.
• It might inadvertently shadow other intended match arms.

Describes the type of administrative action, as follows:

• FILE_SYSTEM_UPDATE - A file system update administrative action initiated from the Amazon FSx console, API (UpdateFileSystem), or CLI (update-file-system).

• STORAGE_OPTIMIZATION - After the FILE_SYSTEM_UPDATE task to increase a file system's storage capacity has been completed successfully, a STORAGE_OPTIMIZATION task starts.

  • For Windows and ONTAP, storage optimization is the process of migrating the file system data to newer larger disks.

  • For Lustre, storage optimization consists of rebalancing the data across the existing and newly added file servers.

  You can track the storage-optimization progress using the ProgressPercent property. When STORAGE_OPTIMIZATION has been completed successfully, the parent FILE_SYSTEM_UPDATE action status changes to COMPLETED. For more information, see Managing storage capacity in the Amazon FSx for Windows File Server User Guide, Managing storage and throughput capacity in the Amazon FSx for Lustre User Guide, and Managing storage capacity and provisioned IOPS in the Amazon FSx for NetApp ONTAP User Guide.

• FILE_SYSTEM_ALIAS_ASSOCIATION - A file system update to associate a new Domain Name System (DNS) alias with the file system. For more information, see AssociateFileSystemAliases.

• FILE_SYSTEM_ALIAS_DISASSOCIATION - A file system update to disassociate a DNS alias from the file system. For more information, see DisassociateFileSystemAliases.

• VOLUME_UPDATE - A volume update to an Amazon FSx for NetApp ONTAP or Amazon FSx for OpenZFS volume initiated from the Amazon FSx console, API (UpdateVolume), or CLI (update-volume).

• VOLUME_RESTORE - An Amazon FSx for OpenZFS volume is returned to the state saved by the specified snapshot, initiated from an API (RestoreVolumeFromSnapshot) or CLI (restore-volume-from-snapshot).

• SNAPSHOT_UPDATE - A snapshot update to an Amazon FSx for OpenZFS volume initiated from the Amazon FSx console, API (UpdateSnapshot), or CLI (update-snapshot).

• RELEASE_NFS_V3_LOCKS - Tracks the release of Network File System (NFS) V3 locks on an Amazon FSx for OpenZFS file system.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

FileSystemAliasAssociation

FileSystemAliasDisassociation

FileSystemUpdate

ReleaseNfsV3Locks

SnapshotUpdate

StorageOptimization

VolumeRestore

VolumeUpdate

Unknown(UnknownVariantValue)

Unknown contains new variants that have been added since this code was generated.
