Struct GptPartition 

pub struct GptPartition { /* private fields */ }

A single partition in a GPT device.

Implementations

impl GptPartition

pub fn new( gpt: &Arc<GptManager>, block_client: Arc<RemoteBlockClient>, info: PartitionInfo, ) -> Arc<Self>

pub async fn terminate(&self)

pub fn update_info(&self, info: PartitionInfo) -> PartitionInfo

Replaces the partition info, returning its old value.

pub fn block_size(&self) -> u32

pub fn block_count(&self) -> u64

pub async unsafe fn attach_vmo(&self, vmo: &Vmo) -> Result<VmoId, Status>

Attaches the VMO.

Safety

The caller must guarantee that the VMO is only attached once. The reason for this is that if the far end suddenly disconnects, it is not safe to assume the VMO will not be written to in any way: the VMO could be the target of an ongoing DMA transfer.

The caller must also ensure that no references are held during I/O as this would be undefined behavior. The caller may hold pointers, which does not lead to undefined behavior; Rust does not make the same assumptions as references for pointers.

pub async fn detach_vmo(&self, vmoid: VmoId) -> Result<(), Status>

pub fn open_passthrough_session(&self, session: ServerEnd<SessionMarker>)

pub fn get_info(&self) -> DeviceInfo

pub async fn read( &self, device_block_offset: u64, block_count: u32, vmo_id: &VmoId, vmo_offset: u64, opts: ReadOptions, trace_flow_id: Option<NonZero<u64>>, ) -> Result<(), Status>

pub async fn write( &self, device_block_offset: u64, block_count: u32, vmo_id: &VmoId, vmo_offset: u64, opts: WriteOptions, trace_flow_id: Option<NonZero<u64>>, ) -> Result<(), Status>

pub async fn flush( &self, trace_flow_id: Option<NonZero<u64>>, ) -> Result<(), Status>

pub async fn trim( &self, device_block_offset: u64, block_count: u32, trace_flow_id: Option<NonZero<u64>>, ) -> Result<(), Status>
