Flags used by devicemapper.

Methods

impl DmFlags

fn empty() -> DmFlags

Returns an empty set of flags.

fn all() -> DmFlags

Returns the set containing all flags.

fn bits(&self) -> __u32

Returns the raw value of the flags currently stored.

fn from_bits(bits: __u32) -> Option<DmFlags>

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

fn from_bits_truncate(bits: __u32) -> DmFlags

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

fn is_all(&self) -> bool

Returns true if all flags are currently set.

fn intersects(&self, other: DmFlags) -> bool

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

fn contains(&self, other: DmFlags) -> bool

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

fn insert(&mut self, other: DmFlags)

Inserts the specified flags in-place.

fn remove(&mut self, other: DmFlags)

Removes the specified flags in-place.

fn toggle(&mut self, other: DmFlags)

Toggles the specified flags in-place.

Trait Implementations

impl Hash for DmFlags

fn hash<__H: Hasher>(&self, __arg_0: &mut __H)

impl Ord for DmFlags

fn cmp(&self, __arg_0: &DmFlags) -> Ordering

This method returns an Ordering between self and other.

impl PartialOrd for DmFlags

fn partial_cmp(&self, __arg_0: &DmFlags) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, __arg_0: &DmFlags) -> bool

This method tests less than (for self and other) and is used by the < operator.
