#[repr(u64)]
pub enum MemAttr {
    Device,
    Normal,
    NormalNonCacheable,
}

Available on AArch64 only.

The memory attributes index field in the descriptor, which is used to index into the MAIR (Memory Attribute Indirection Register).

Variants

Device

Device-nGnRE memory

Normal

Normal memory

NormalNonCacheable

Normal non-cacheable memory

Implementations

impl MemAttr

pub const MAIR_VALUE: u64 = 4_521_732u64

The MAIR_ELx register should be set to this value to match the memory attributes in the descriptors.

Trait Implementations

impl Clone for MemAttr

fn clone(&self) -> MemAttr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MemAttr

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

Formats the value using the given formatter.

impl PartialEq<MemAttr> for MemAttr

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

This method tests for self and other values to be equal, and is used by ==.

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

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