Struct PagePerms 

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

Uses Linux protection bits so mapping operations need no second permission model.

Implementations

impl PagePerms

pub const READ: Self

Allows guest reads from a page.

pub const WRITE: Self

Allows guest writes to a page.

pub const EXEC: Self

Allows guest instruction fetches from a page.

pub const fn empty() -> Self

Creates permissions that deny all guest accesses.

pub const fn bits(self) -> u8

Returns the three permission bits used by generated code.

pub const fn from_bits(bits: u8) -> Self

Creates permissions and removes bits that this MMU does not support.

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

Tests whether all permissions in other are present.

Trait Implementations

impl BitOr for PagePerms

type Output = PagePerms

The resulting type after applying the | operator.

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

Performs the | operation.

impl BitOrAssign for PagePerms

fn bitor_assign(&mut self, rhs: Self)

Performs the |= operation.

impl Clone for PagePerms

fn clone(&self) -> PagePerms

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for PagePerms

impl Debug for PagePerms

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

Formats the value using the given formatter.

impl Eq for PagePerms

impl PartialEq for PagePerms

fn eq(&self, other: &PagePerms) -> 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.
