Methods

impl DmCookie

pub const DM_UDEV_DISABLE_DM_RULES_FLAG: DmCookie

Disable subsystem udev rules, but allow general DM udev rules to run.

pub const DM_UDEV_DISABLE_DISK_RULES_FLAG: DmCookie

Disable dm udev rules which create symlinks in /dev/disk/* directory.

pub const DM_UDEV_DISABLE_OTHER_RULES_FLAG: DmCookie

Disable all rules that are not general dm nor subsystem related.

pub const DM_UDEV_LOW_PRIORITY_FLAG: DmCookie

Instruct udev rules to give lower priority to the device.

pub const DM_UDEV_DISABLE_LIBRARY_FALLBACK: DmCookie

Disable libdevmapper's node management.

pub const DM_UDEV_PRIMARY_SOURCE_FLAG: DmCookie

Automatically appended to all IOCTL calls issues by libdevmapper for generating udev uevents.

pub const fn empty() -> DmCookie

Returns an empty set of flags

pub const fn intersects(&self, other: DmCookie) -> bool

Returns true if there are flags common to both self and other.

pub const fn contains(&self, other: DmCookie) -> bool

Returns true all of the flags in other are contained within self.

pub fn insert(&mut self, other: DmCookie)

Inserts the specified flags in-place.
