Block size for allocations within the thin pool

low_water_mark: DataBlocks

Amount of free space left at which to trigger the low water mark

feature_args: HashSet<String>

Feature arguments

Implementations

impl ThinPoolTargetParams

pub fn new( metadata_dev: Device, data_dev: Device, data_block_size: Sectors, low_water_mark: DataBlocks, feature_args: Vec<String> ) -> ThinPoolTargetParams

Create a new ThinPoolTargetParams struct

Trait Implementations

impl Clone for ThinPoolTargetParams

fn clone(&self) -> ThinPoolTargetParams

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ThinPoolTargetParams

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

Formats the value using the given formatter.

impl Display for ThinPoolTargetParams

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

Formats the value using the given formatter.

impl FromStr for ThinPoolTargetParams

type Err = DmError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> DmResult<ThinPoolTargetParams>

Parses a string s to return a value of this type.

impl PartialEq for ThinPoolTargetParams

fn eq(&self, other: &ThinPoolTargetParams) -> 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 TargetParams for ThinPoolTargetParams

fn param_str(&self) -> String

Return the param string only

fn target_type(&self) -> TargetTypeBuf

Return the target type

impl Eq for ThinPoolTargetParams
