Required Methods

fn on_attach_vmo( self: Arc<Self>, vmo: &Arc<Vmo>, ) -> impl Future<Output = Result<(), Status>> + Send

fn open_session( self: Arc<Self>, stream: SessionRequestStream, offset_map: Option<OffsetMap>, block_size: u32, ) -> impl Future<Output = Result<(), Error>> + Send

Creates a new session to handle stream. The returned future should run until the session completes, for example when the client end closes. If offset_map is set, it will be used to remap the dev_offset of FIFO requests.

fn get_info( &self, ) -> impl Future<Output = Result<Cow<'_, DeviceInfo>, Status>> + Send

Called to get block/partition information for Block::GetInfo, Partition::GetTypeGuid, etc.

Provided Methods

fn get_volume_info( &self, ) -> impl Future<Output = Result<(VolumeManagerInfo, VolumeInfo), Status>> + Send

Called to handle the GetVolumeInfo FIDL call.

fn query_slices( &self, _start_slices: &[u64], ) -> impl Future<Output = Result<Vec<VsliceRange>, Status>> + Send

Called to handle the QuerySlices FIDL call.

fn extend( &self, _start_slice: u64, _slice_count: u64, ) -> impl Future<Output = Result<(), Status>> + Send

Called to handle the Shrink FIDL call.

fn shrink( &self, _start_slice: u64, _slice_count: u64, ) -> impl Future<Output = Result<(), Status>> + Send

Called to handle the Shrink FIDL call.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
