Struct kernel::mem::address::virtual_address::VirtualAddress

pub struct VirtualAddress {
    bits: usize,
}

The VirtualAddress struct represents a 39-bit virtual address defined in the Sv39 page table format.

Fields

bits: usize

Implementations

impl VirtualAddress

pub fn floor(&self) -> PageNumber

Returns the PageNumber that represents the page that contains the virtual address.

pub fn ceil(&self) -> PageNumber

Returns the PageNumber that represents the page that contains the virtual address, rounding up to the next frame if the physical address is not aligned to a frame.

pub fn page_offset(&self) -> usize

Returns the byte offset of the virtual address within its containing page.

pub fn is_aligned(&self) -> bool

Returns true if the virtual address is aligned to a page.

pub fn as_ptr(&self) -> *const u8

Returns a raw pointer to the virtual address.

pub fn as_ptr_mut(&self) -> *mut u8

Returns a mutable raw pointer to the virtual address.

Trait Implementations

impl Add<usize> for VirtualAddress

type Output = VirtualAddress

The resulting type after applying the + operator.

fn add(self, rhs: usize) -> Self

Performs the + operation.

impl AddAssign<usize> for VirtualAddress

fn add_assign(&mut self, rhs: usize)

Performs the += operation.

impl Clone for VirtualAddress

fn clone(&self) -> VirtualAddress

Returns a copy of the value.

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

Performs copy-assignment from source.

impl From<PageNumber> for VirtualAddress

fn from(value: PageNumber) -> Self

Converts to this type from the input type.

impl From<VirtualAddress> for PageNumber

fn from(value: VirtualAddress) -> Self

Converts to this type from the input type.

impl From<VirtualAddress> for usize

fn from(value: VirtualAddress) -> Self

Converts to this type from the input type.

impl From<usize> for VirtualAddress

fn from(value: usize) -> Self

Converts to this type from the input type.

impl Ord for VirtualAddress

fn cmp(&self, other: &VirtualAddress) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<VirtualAddress> for VirtualAddress

fn eq(&self, other: &VirtualAddress) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<VirtualAddress> for VirtualAddress

fn partial_cmp(&self, other: &VirtualAddress) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Sub<usize> for VirtualAddress

type Output = VirtualAddress

The resulting type after applying the - operator.

fn sub(self, rhs: usize) -> Self

Performs the - operation.
