pub struct VolumeSynchronousProxy { /* private fields */ }

Implementations

impl VolumeSynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

pub fn wait_for_event( &self, deadline: MonotonicInstant, ) -> Result<VolumeEvent, 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 get_info( &self, ___deadline: MonotonicInstant, ) -> Result<BlockGetInfoResult, Error>

Get information about the underlying block device.

pub fn get_stats( &self, clear: bool, ___deadline: MonotonicInstant, ) -> Result<BlockGetStatsResult, Error>

Returns stats about block device operations. Setting clear will reset stats counters.

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

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

pub fn get_type_guid( &self, ___deadline: MonotonicInstant, ) -> Result<(i32, Option<Box<Guid>>), Error>

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, ___deadline: MonotonicInstant, ) -> Result<(i32, Option<Box<Guid>>), Error>

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, ___deadline: MonotonicInstant, ) -> Result<(i32, Option<String>), Error>

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

pub fn get_metadata( &self, ___deadline: MonotonicInstant, ) -> Result<PartitionGetMetadataResult, Error>

Gets the metadata for the partition.

Fields may be absent if the partition doesn’t have the given metadata.

pub fn query_slices( &self, start_slices: &[u64], ___deadline: MonotonicInstant, ) -> Result<(i32, [VsliceRange; 16], u64), Error>

Returns the number of contiguous allocated (or unallocated) vslices starting from each vslice.

pub fn get_volume_info( &self, ___deadline: MonotonicInstant, ) -> Result<(i32, Option<Box<VolumeManagerInfo>>, Option<Box<VolumeInfo>>), Error>

Returns the information about this volume and the volume manager it is embedded in.

pub fn extend( &self, start_slice: u64, slice_count: u64, ___deadline: MonotonicInstant, ) -> Result<i32, Error>

Extends the mapping of this partition.

The ability to extend the partition is dependent on having sufficient free space on the underlying device, having sufficient free slots for tracking the bytes in the volume manager header, and the partition limit (see VolumeManager.SetPartitionLimit).

pub fn shrink( &self, start_slice: u64, slice_count: u64, ___deadline: MonotonicInstant, ) -> Result<i32, Error>

Shrinks a virtual partition. Returns ZX_OK if ANY slices are freed, even if part of the requested range contains unallocated slices.

pub fn destroy(&self, ___deadline: MonotonicInstant) -> Result<i32, Error>

Destroys the current partition, removing it from the VolumeManager, and freeing all underlying storage. The connection to the volume is also closed.
