Struct XpermsBitmap 

pub struct XpermsBitmap(/* private fields */);

256-bit bitmap used for extended permissions (such as ioctls and netlink messages).

Implementations

impl XpermsBitmap

pub const BITMAP_BLOCKS: usize = XPERMS_BITMAP_BLOCKS

pub const ALL: Self

Bitmap with all 256 bits set to 1.

pub const NONE: Self

Empty bitmap with all bits set to 0.

pub fn new(elements: [u64; 4]) -> Self

Constructs a new XpermsBitmap from an array of four 64-bit words.

pub fn contains(&self, value: u8) -> bool

Returns true if the bit corresponding to value is set in this bitmap.

pub fn from_atomics(atomics: &[AtomicU64; 4]) -> Self

Constructs an XpermsBitmap by loading words from an array of atomic 64-bit integers using relaxed ordering.

pub fn to_atomics(&self, atomics: &[AtomicU64; 4])

Stores this bitmap into an array of atomic 64-bit integers using relaxed ordering.

Trait Implementations

impl BitAnd for XpermsBitmap

type Output = XpermsBitmap

The resulting type after applying the & operator.

fn bitand(self, rhs: Self) -> Self::Output

Performs the & operation.

impl BitAndAssign for XpermsBitmap

fn bitand_assign(&mut self, rhs: Self)

Performs the &= operation.

impl BitOr for XpermsBitmap

type Output = XpermsBitmap

The resulting type after applying the | operator.

fn bitor(self, rhs: Self) -> Self::Output

Performs the | operation.

impl BitOrAssign for XpermsBitmap

fn bitor_assign(&mut self, rhs: Self)

Performs the |= operation.

impl Clone for XpermsBitmap

fn clone(&self) -> XpermsBitmap

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for XpermsBitmap

impl Debug for XpermsBitmap

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

Formats the value using the given formatter.

impl Eq for XpermsBitmap

impl Hash for XpermsBitmap

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 Not for XpermsBitmap

type Output = XpermsBitmap

The resulting type after applying the ! operator.

fn not(self) -> Self::Output

Performs the unary ! operation.

impl PartialEq for XpermsBitmap

fn eq(&self, other: &XpermsBitmap) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Sub for XpermsBitmap

type Output = XpermsBitmap

The resulting type after applying the - operator.

fn sub(self, rhs: Self) -> Self

Performs the - operation.

impl SubAssign for XpermsBitmap

fn sub_assign(&mut self, rhs: Self)

Performs the -= operation.
