Struct devicemapper::LinearDevTargetTable

pub struct LinearDevTargetTable {
    pub table: Vec<TargetLine<LinearDevTargetParams>>,
}

A target table for a linear device. Such a table allows flakey targets as well as linear targets.

Fields

table: Vec<TargetLine<LinearDevTargetParams>>

The device's table

Methods

impl LinearDevTargetTable

pub fn new(
    table: Vec<TargetLine<LinearDevTargetParams>>
) -> LinearDevTargetTable

Make a new LinearDevTargetTable from a suitable vec

Trait Implementations

impl DmDevice<LinearDevTargetTable> for LinearDev

fn device(&self) -> Device

The device.

fn devnode(&self) -> PathBuf

The device's device node.

fn equivalent_tables(
    left: &LinearDevTargetTable,
    right: &LinearDevTargetTable
) -> 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) -> &LinearDevTargetTable

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.

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
