A trait capturing some shared properties of DM devices.

Required methods

fn device(&self) -> Device

The device.

fn devnode(&self) -> PathBuf

The device's device node.

fn equivalent_tables(left: &T, right: &T) -> DmResult<bool>

Check if tables indicate an equivalent device.

fn name(&self) -> &DmName

The device's name.

fn size(&self) -> Sectors

The number of sectors available for user data.

fn table(&self) -> &T

What the device thinks its table is.

fn teardown(&mut self, dm: &DM) -> DmResult<()>

Erase the kernel's memory of this device.

fn uuid(&self) -> Option<&DmUuid>

The device's UUID, if available. Note that the UUID is not any standard UUID format.

Provided methods

fn read_kernel_table(dm: &DM, id: &DevId) -> DmResult<T>

Read the devicemapper table

fn resume(&mut self, dm: &DM) -> DmResult<()>

Resume I/O on the device.

fn suspend(&mut self, dm: &DM, flush: bool) -> DmResult<()>

Suspend I/O on the device. If flush is true, flush the device first.

fn table_load(&self, dm: &DM, table: &T) -> DmResult<()>

Load a table
