Struct FileBackedVolumeProviderSynchronousProxy

pub struct FileBackedVolumeProviderSynchronousProxy { /* private fields */ }

Implementations

impl FileBackedVolumeProviderSynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

pub fn wait_for_event( &self, deadline: MonotonicInstant, ) -> Result<FileBackedVolumeProviderEvent, Error>

Waits until an event arrives and returns it. It is safe for other threads to make concurrent requests while waiting for an event.

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.
