Struct fidl_fuchsia_hardware_block_partition::PartitionProxy

pub struct PartitionProxy { /* private fields */ }

Implementations

impl PartitionProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for Partition

pub fn take_event_stream(&self) -> PartitionEventStream

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

Panics

Panics if the event stream was already taken.

pub fn get_info(&self) -> QueryResponseFut<BlockGetInfoResult>

Get information about the underlying block device.

pub fn get_stats(&self, clear: bool) -> QueryResponseFut<BlockGetStatsResult>

Returns stats about the block device on the provided buffer and optionally clears the counters.

storage_metrics.CallStat.bytes_transferred is number of bytes requested to be transferred.

pub fn open_session( &self, session: ServerEnd<SessionMarker> ) -> Result<(), Error>

Opens a new FIFO-based session on the block device.

pub fn read_blocks( &self, vmo: Vmo, length: u64, dev_offset: u64, vmo_offset: u64 ) -> QueryResponseFut<BlockReadBlocksResult>

Reads from a block device.

This read does not require exclusive access. length, dev_offset and vmo_offset are specified in bytes, but they must be block-aligned. This method is provided for backward compatibility, and is not intended for new code. New code should use the FIFO interface along with the client libraries to read and write from block devices.

pub fn write_blocks( &self, vmo: Vmo, length: u64, dev_offset: u64, vmo_offset: u64 ) -> QueryResponseFut<BlockWriteBlocksResult>

Writes to a block device.

This write does not require exclusive access. length, dev_offset and vmo_offset are specified in bytes, but they must be block-aligned. This method is provided for backward compatibility, and is not intended for new code. New code should use the FIFO interface along with the client libraries to read and write from block devices.

pub fn get_type_guid(&self) -> QueryResponseFut<(i32, Option<Box<Guid>>)>

Gets the type GUID of the partition (if one exists). If the partition has no type GUID, ZX_ERR_NOT_SUPPORTED is returned.

pub fn get_instance_guid(&self) -> QueryResponseFut<(i32, Option<Box<Guid>>)>

Gets the instance GUID of the partition (if one exists). If the partition has no instance GUID, ZX_ERR_NOT_SUPPORTED is returned.

pub fn get_name(&self) -> QueryResponseFut<(i32, Option<String>)>

Gets the name of the partition (if one exists). If the partition has no name, ZX_ERR_NOT_SUPPORTED is returned.
