Struct MemoryRegion 

#[repr(C)]
pub struct MemoryRegion {
    pub base_addr: u64,
    pub size: u64,
    pub permissions: u32,
    pub cache_policy: u32,
}

Memory region descriptor for shared memory transfers

Fields

base_addr: u64

Base virtual address

size: u64

Size of the region in bytes

permissions: u32

Memory permissions (read/write/execute)

cache_policy: u32

Cache policy (write-back, write-through, uncached)

Implementations

impl MemoryRegion

pub const fn new(base_addr: u64, size: u64) -> Self

Create a new memory region descriptor

pub fn with_permissions(self, permissions: u32) -> Self

Set permissions for the region

pub fn with_cache_policy(self, policy: u32) -> Self

Set cache policy for the region

impl MemoryRegion

pub fn from_shared(region: &SharedRegion, vaddr: VirtualAddress) -> Self

Create from a SharedRegion

Trait Implementations

impl Clone for MemoryRegion

fn clone(&self) -> MemoryRegion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MemoryRegion

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

Formats the value using the given formatter.

impl PartialEq for MemoryRegion

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