Struct kernel::mem::address::physical_address::PhysicalAddress

pub struct PhysicalAddress {
    bits: usize,
}

The PhysicalAddress struct represents a 56-bit physical address defined in the Sv39 page table format.

Fields

bits: usize

Implementations

impl PhysicalAddress

pub fn floor(&self) -> FrameNumber

Returns the FrameNumber that represents the frame that contains the physical address.

pub fn ceil(&self) -> FrameNumber

Returns the FrameNumber that represents the frame that contains the physical 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 physical address within its containing frame.

pub fn is_aligned(&self) -> bool

Returns true if the physical address is aligned to a frame.

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

Returns a raw pointer to the physical address.

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

Returns a mutable raw pointer to the physical address.

pub fn as_ref<T>(&self) -> &'static T

pub fn as_mut<T>(&self) -> &'static mut T

Trait Implementations

impl Add<usize> for PhysicalAddress

type Output = PhysicalAddress

The resulting type after applying the + operator.

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

Performs the + operation.

impl Clone for PhysicalAddress

fn clone(&self) -> PhysicalAddress

Returns a copy of the value.

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

Performs copy-assignment from source.

impl From<FrameNumber> for PhysicalAddress

fn from(value: FrameNumber) -> Self

Converts to this type from the input type.

impl From<PhysicalAddress> for FrameNumber

fn from(value: PhysicalAddress) -> Self

Converts to this type from the input type.

impl From<PhysicalAddress> for usize

fn from(value: PhysicalAddress) -> Self

Converts to this type from the input type.

impl From<usize> for PhysicalAddress

fn from(value: usize) -> Self

Converts to this type from the input type.

impl Ord for PhysicalAddress

fn cmp(&self, other: &PhysicalAddress) -> 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<PhysicalAddress> for PhysicalAddress

fn eq(&self, other: &PhysicalAddress) -> 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<PhysicalAddress> for PhysicalAddress

fn partial_cmp(&self, other: &PhysicalAddress) -> 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 PhysicalAddress

type Output = PhysicalAddress

The resulting type after applying the - operator.

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

Performs the - operation.
