Enum AccessPermission 

pub enum AccessPermission {
    PrivilegedReadWrite = 0,
    ReadWrite = 1,
    PrivilegedReadOnly = 2,
    ReadOnly = 3,
}

Access permissions for Stage 1 translation using Direct permissions Based on ARM DDI 0487K.a Table D8-49

Variants

PrivilegedReadWrite = 0

Read/write access for privileged level only, no access for unprivileged AP[2:1] = 0b00 (when supporting two privilege levels) For single privilege level: Read/write access

ReadWrite = 1

Read/write access for both privileged and unprivileged levels AP[2:1] = 0b01

PrivilegedReadOnly = 2

Read-only access for privileged level only, no access for unprivileged AP[2:1] = 0b10 (when supporting two privilege levels) For single privilege level: Read-only access

ReadOnly = 3

Read-only access for both privileged and unprivileged levels AP[2:1] = 0b11

Implementations

impl AccessPermission

pub const fn as_bits(self) -> u8

Get the AP field value for the TTE

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

Create from AP bits

pub const fn allows_unprivileged(self) -> bool

Check if this permission allows unprivileged access

pub const fn allows_privileged_write(self) -> bool

Check if this permission allows write access at the privileged level

pub const fn allows_unprivileged_write(self) -> bool

Check if this permission allows write access at the unprivileged level

Trait Implementations

impl Clone for AccessPermission

fn clone(&self) -> AccessPermission

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AccessPermission

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

Formats the value using the given formatter.

impl Hash for AccessPermission

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 PartialEq for AccessPermission

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