Struct devicemapper::Device

pub struct Device {
    pub major: u32,
    pub minor: u32,
}

A struct containing the device’s major and minor numbers

Also allows conversion to/from a single 64bit dev_t value.

Fields

major: u32

Device major number

minor: u32

Device minor number

Implementations

impl Device

The Linux kernel’s kdev_t encodes major/minor values as mmmM MMmm.

pub fn from_kdev_t(val: u32) -> Device

Make a Device from a kdev_t.

pub fn to_kdev_t(self) -> Option<u32>

Convert to a kdev_t. Return None if values are not expressible as a kdev_t.

Trait Implementations

impl Clone for Device

fn clone(&self) -> Device

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Device

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

Formats the value using the given formatter.

impl Display for Device

Display format is the device number in “:” format

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

Formats the value using the given formatter.

impl From<Device> for dev_t

fn from(dev: Device) -> dev_t

Converts to this type from the input type.

impl From<u64> for Device

fn from(val: dev_t) -> Device

Converts to this type from the input type.

impl FromStr for Device

type Err = DmError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Device, DmError>

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

impl Hash for Device

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Device

fn eq(&self, other: &Device) -> 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.
