Struct FileBackedVolumeProviderProxy

pub struct FileBackedVolumeProviderProxy { /* private fields */ }

Implementations

impl FileBackedVolumeProviderProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.fxfs/FileBackedVolumeProvider.

pub fn take_event_stream(&self) -> FileBackedVolumeProviderEventStream

Get a Stream of events from the remote end of the protocol.

Panics

Panics if the event stream was already taken.

pub fn open( &self, parent_directory_token: Handle, name: &str, server_end: ServerEnd<VolumeMarker>, ) -> Result<(), Error>

Opens a file as a block device and starts serving block requests.

name must refer to an existing file in the directory represented by parent_directory_token.

The block size of the device will match the underlying filesystem’s block size. If the file’s size is not a multiple of the block size, the apparent size of the device will be rounded down.

parent_directory_token is a token obtained via fuchsia.io.Directory/GetToken. The directory connection must have the MODIFY_DIRECTORY right.

Errors will be sent as an epitaph on server_end.
