Struct Vmar 

pub struct Vmar {
    base: VirtAddr,
    size: usize,
    children: Mutex<Vec<VmarChild>>,
}

Virtual Memory Address Region (VMAR)

Manages a region of virtual address space, similar to Asterinas VMAR. Used for process address space management.

Fields

base: VirtAddr

Base virtual address

size: usize

Size of the region

children: Mutex<Vec<VmarChild>>

Child regions

Implementations

impl Vmar

pub fn new(base: VirtAddr, size: usize) -> Self

Creates a new VMAR

pub fn base(&self) -> VirtAddr

Returns the base virtual address

pub fn size(&self) -> usize

Returns the size of the region

pub fn alloc( &self, offset: usize, size: usize, flags: MapFlags, ) -> Result<VirtAddr, MapError>

Allocates a new region within this VMAR

pub fn dealloc(&self, offset: usize) -> Result<(), MapError>

Deallocates a region within this VMAR

Trait Implementations

impl Debug for Vmar

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

Performs the fmt operation.
