Enum MemoryAttributes

pub enum MemoryAttributes {
    StronglyOrdered,
    Device {
        shareable: bool,
    },
    Normal {
        shareable: bool,
        cache_policy: CachePolicy,
    },
}

Describes memory type, cache policy, and shareability.

Variants

StronglyOrdered

Shareable, non-cached, strongly-ordered memory region.

Device

Non-cached device peripheral region.

Fields

shareable: bool

Whether the region is accessible by more than one bus master (eg. a DMA engine or a second MCU core).

Normal

Normal memory region (ie. “actual” memory, such as Flash or SRAM).

Fields

shareable: bool

Whether the region is accessible by more than one bus master (eg. a DMA engine or a second MCU core).

cache_policy: CachePolicy

How this region should be cached (?).

Trait Implementations

impl Clone for MemoryAttributes

fn clone(&self) -> MemoryAttributes

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MemoryAttributes

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

Formats the value using the given formatter.

impl PartialEq for MemoryAttributes

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