Struct Filesystem

pub struct Filesystem { /* private fields */ }

Asynchronously manages a block device for filesystem operations.

Implementations

impl Filesystem

pub fn config(&self) -> &dyn FSConfig

pub fn into_config(self) -> Box<dyn FSConfig>

pub fn new<B: BlockConnector + 'static, FSC: FSConfig>( block_connector: B, config: FSC, ) -> Self

Creates a new Filesystem.

pub fn from_boxed_config( block_connector: Box<dyn BlockConnector>, config: Box<dyn FSConfig>, ) -> Self

Creates a new Filesystem.

pub fn get_component_moniker(&self) -> Option<String>

If the filesystem is a currently running component, returns its (relative) moniker.

pub async fn format(&mut self) -> Result<(), Error>

Calls fuchsia.fs.startup/Startup.Format on the configured filesystem component.

Which component is used and the options passed to it are controlled by the config this Filesystem was created with.

See FSConfig.

Errors

Returns any errors from the Format method. Also returns an error if the startup protocol is not found, if it couldn’t launch or find the filesystem component, or if it couldn’t get the block device channel.

pub async fn fsck(&mut self) -> Result<(), Error>

Calls fuchsia.fs.startup/Startup.Check on the configured filesystem component.

Which component is used and the options passed to it are controlled by the config this Filesystem was created with.

See FSConfig.

Errors

Returns any errors from the Check method. Also returns an error if the startup protocol is not found, if it couldn’t launch or find the filesystem component, or if it couldn’t get the block device channel.

pub async fn serve(&mut self) -> Result<ServingSingleVolumeFilesystem, Error>

Serves the filesystem on the block device and returns a ServingSingleVolumeFilesystem representing the running filesystem component.

Errors

Returns Err if serving the filesystem failed.

pub async fn serve_multi_volume( &mut self, ) -> Result<ServingMultiVolumeFilesystem, Error>

Serves the filesystem on the block device and returns a ServingMultiVolumeFilesystem representing the running filesystem component. No volumes are opened; clients have to do that explicitly.

Errors

Returns Err if serving the filesystem failed.
