start: Option<VirtAddr>

len: usize

backing: Backing

perms: Perms

Implementations

impl Region

pub fn new( start: Option<VirtAddr>, len: usize, backing: Backing, perms: Perms, ) -> Self

Creates a new region.

• start is the starting virtual address of the region. If None, the system will choose a suitable address.
• len is the length of the region in bytes.
• backing is the backing type of the region, which determines how the region is initialized and where its contents come from.
• perms is the permissions of the region, which determines how the region can be accessed.

pub fn start(&self) -> VirtAddr

pub fn len(&self) -> usize

pub fn contains(&self, addr: VirtAddr) -> bool

Trait Implementations

impl Clone for Region

fn clone(&self) -> Region

Returns a duplicate of the value.

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

Performs copy-assignment from source.
