#[repr(u8)]
pub enum Permissions {
    No = 0,
    Read = 1,
    Write = 2,
    ReadWrite = 3,
}

Permissions for accessing virtual memory.

Variants

No = 0

Implementations

impl Permissions

pub fn allow(&self, access: Self) -> bool

Check whether the permissions self allow the given access.

pub fn has_write(&self) -> bool

Check whether the permissions self include write access.

Trait Implementations

impl BitAnd for Permissions

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

Return the intersection of self and rhs.

type Output = Permissions

The resulting type after applying the & operator.

impl BitOr for Permissions

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

Return the union of self and rhs.

type Output = Permissions

The resulting type after applying the | operator.

impl Clone for Permissions

fn clone(&self) -> Permissions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Permissions

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

Formats the value using the given formatter.

impl PartialEq for Permissions

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