pub fn new( start: Sectors, length: Sectors, params: CacheTargetParams ) -> CacheDevTargetTable

Make a new CacheDevTargetTable from the required input

Trait Implementations

impl Clone for CacheDevTargetTable

fn clone(&self) -> CacheDevTargetTable

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CacheDevTargetTable

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for CacheDevTargetTable

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl DmDevice<CacheDevTargetTable> for CacheDev

fn device(&self) -> Device

The device.

fn devnode(&self) -> PathBuf

The device’s device node.

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

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, options: DmOptions) -> DmResult<()>

Suspend I/O on the device.

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

Load a table

impl PartialEq for CacheDevTargetTable

fn eq(&self, other: &CacheDevTargetTable) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TargetTable for CacheDevTargetTable

fn from_raw_table( table: &[(u64, u64, String, String)] ) -> DmResult<CacheDevTargetTable>

Constructs a table from a raw table returned by DM::table_status()

fn to_raw_table(&self) -> Vec<(u64, u64, String, String)>

Generates a table that can be loaded by DM::table_load()
