Struct RootVolume 

pub struct RootVolume { /* private fields */ }

RootVolume is the top-level volume which stores references to all of the other Volumes.

Implementations

impl RootVolume

pub fn volume_directory(&self) -> &Directory<ObjectStore>

pub async fn new_volume( &self, volume_name: &str, options: NewChildStoreOptions, ) -> Result<Arc<ObjectStore>, Error>

Creates a new volume under a transaction lock.

pub async fn volume( &self, volume_name: &str, options: StoreOptions, ) -> Result<Arc<ObjectStore>, Error>

Returns the volume with the given name. This is not thread-safe.

pub async fn delete_volume( &self, volume_name: &str, transaction: Transaction<'_>, callback: impl FnOnce() + Send, ) -> Result<(), Error>

Deletes the given volume. Consumes transaction and runs callback during commit. The caller must have the correct locks for the volumes directory.

pub async fn install_volume( &self, src: &str, image_file: &str, dst: &str, ) -> Result<(), Error>

Attempts to install the image image_file in the volume src as the volume dst. The image file should be an fxfs partition image containing a volume matching the name dst. The contents of the dst volume in the image will be installed in-place into this filesystem, replacing an existing dst volume if one exists.

There can be no other objects in src with extent records, and neither src nor dst can be encrypted.

pub async fn acquire_transaction_for_remove_volume( &self, name: &str, extra_keys: impl IntoIterator<Item = LockKey>, allow_not_found: bool, ) -> Result<(u64, Transaction<'_>), Error>

Acquires a transaction with appropriate locks to remove volume |name|. Also returns the object ID of the store which will be deleted.
