Struct devicemapper::Device
[−]
[src]
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
Methods
impl Device
[src]
The Linux kernel's kdev_t encodes major/minor values as mmmM MMmm.
fn from_kdev_t(val: u32) -> Device
[src]
Make a Device from a kdev_t.
fn to_kdev_t(&self) -> Option<u32>
[src]
Convert to a kdev_t. Return None if values are not expressible as a kdev_t.
