pub fn new(channel: Channel) -> Self
pub fn into_channel(self) -> Channel
sourcepub fn wait_for_event(
&self,
deadline: Time
) -> Result<VolumeManagerEvent, Error>
pub fn wait_for_event( &self, deadline: Time ) -> Result<VolumeManagerEvent, Error>
Waits until an event arrives and returns it. It is safe for other threads to make concurrent requests while waiting for an event.
sourcepub fn allocate_partition(
&self,
slice_count: u64,
type_: &mut Guid,
instance: &mut Guid,
name: &str,
flags: u32,
___deadline: Time
) -> Result<i32, Error>
pub fn allocate_partition( &self, slice_count: u64, type_: &mut Guid, instance: &mut Guid, name: &str, flags: u32, ___deadline: Time ) -> Result<i32, Error>
Allocates a virtual partition with the requested features.
slice_count is the number of slices initially allocated to the partition, at
offset zero. The number of slices allocated to a new partition must be at least one.
type and value indicate type and instance GUIDs for the partition, respectively.
name indicates the name of the new partition.
sourcepub fn get_info(
&self,
___deadline: Time
) -> Result<(i32, Option<Box<VolumeManagerInfo>>), Error>
pub fn get_info( &self, ___deadline: Time ) -> Result<(i32, Option<Box<VolumeManagerInfo>>), Error>
Gets the VolumeManagerInfo describing this instance of the VolumeManager.
sourcepub fn activate(
&self,
old_guid: &mut Guid,
new_guid: &mut Guid,
___deadline: Time
) -> Result<i32, Error>
pub fn activate( &self, old_guid: &mut Guid, new_guid: &mut Guid, ___deadline: Time ) -> Result<i32, Error>
Atomically marks a vpartition (by instance GUID) as inactive, while finding another partition (by instance GUID) and marking it as active.
If the “old” partition does not exist, the GUID is ignored.
If the “old” partition is the same as the “new” partition, the “old”
GUID is ignored.
If the “new” partition does not exist, ZX_ERR_NOT_FOUND is returned.
This function does not destroy the “old” partition, it just marks it as inactive – to reclaim that space, the “old” partition must be explicitly destroyed. This destruction can also occur automatically when the FVM driver is rebound (i.e., on reboot).
This function may be useful for A/B updates within the FVM, since it will allow activating updated partitions.
sourcepub fn get_partition_limit(
&self,
guid: &mut Guid,
___deadline: Time
) -> Result<(i32, u64), Error>
pub fn get_partition_limit( &self, guid: &mut Guid, ___deadline: Time ) -> Result<(i32, u64), Error>
Retrieves the allocation limit for the partition. A return value of 0 indicates that there is no limit and the partition can be extended as long as there is available space on the device.
The partition may be larger than this limit if a smaller limit was applied after the partition had already grown to the current size.
Currently the partition limit is not persisted across reboots but this may change in the future.
sourcepub fn set_partition_limit(
&self,
guid: &mut Guid,
slice_count: u64,
___deadline: Time
) -> Result<i32, Error>
pub fn set_partition_limit( &self, guid: &mut Guid, slice_count: u64, ___deadline: Time ) -> Result<i32, Error>
Sets the allocation limit for the partition. Partitions can not be extended beyond their allocation limit. The partition limit will never shrink partitions so if this value is less than the current partition size, it will keep the current size but prevent further growth.
The allocation limits are on the VolumeManager API rather than on the partition because they represent a higher capability level. These limits are designed to put guards on users of the block device (and hence the Volume API).
Currently the partition limit is not persisted across reboots but this may change in the future.
sourcepub fn set_partition_name(
&self,
guid: &mut Guid,
name: &str,
___deadline: Time
) -> Result<VolumeManagerSetPartitionNameResult, Error>
pub fn set_partition_name( &self, guid: &mut Guid, name: &str, ___deadline: Time ) -> Result<VolumeManagerSetPartitionNameResult, Error>
Renames the specified partition. Any existing devices that include the name of the partition in their topological path might not reflect the name change until the next time that the device is instantiated.
