MPU Memory Attributes

Fields

shareable: bool

Shareable

cacheable: bool

Cacheable

bufferable: bool

Bufferable

execute_never: bool

Execute Never (XN)

Implementations

impl MPUAttributes

pub fn normal() -> Self

Normal memory (cacheable, bufferable)

pub fn device() -> Self

Device memory (non-cacheable, bufferable)

Per ARM architecture: Device memory has TEX=0b000, C=0, B=1. This distinguishes it from Strongly-ordered (TEX=0b000, C=0, B=0).

pub fn strongly_ordered() -> Self

Strongly-ordered memory

Trait Implementations

impl Clone for MPUAttributes

fn clone(&self) -> MPUAttributes

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for MPUAttributes

impl Debug for MPUAttributes

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

Formats the value using the given formatter.

impl Eq for MPUAttributes

impl PartialEq for MPUAttributes

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