Struct devicemapper::Device

pub struct Device {
    pub major: u32,
    pub minor: u8,
}

A struct containing the device's major and minor numbers

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

Fields

major: u32

Device major number

minor: u8

Device minor number

Methods

impl Device

fn path(&self) -> Option<PathBuf>

Returns the path in /dev that corresponds with the device number.

fn dstr(&self) -> String
