Struct PhysicalAddress 

#[repr(transparent)]
pub struct PhysicalAddress(MemoryAddress);

Physical memory address.

A thin wrapper around MemoryAddress that denotes physical addresses (host RAM / MMIO). Like VirtualAddress, this type carries intent and prevents accidental VA↔PA mix-ups.

Semantics

• Use PhysicalAddress::page / PhysicalAddress::offset / PhysicalAddress::split to derive the page base and in-page offset for a concrete PageSize.
• Combine a PhysicalPage<S> with a MemoryAddressOffset<S> using PhysicalPage::join to reconstruct the original PhysicalAddress.

Notes

• Page-table entries often store a page-aligned physical base (low S::SHIFT bits cleared) plus per-entry flag bits; use split::<S>() to reason about base vs. offset explicitly.

Examples

let pa = PhysicalAddress::new(0x0000_0010_2000_0042);
let (pp, off) = pa.split::<Size4K>();
assert_eq!(pp.base().as_u64() & (Size4K::SIZE - 1), 0);
assert_eq!(pp.join(off).as_u64(), pa.as_u64());

Trait Implementations

impl Clone for PhysicalAddress

fn clone(&self) -> PhysicalAddress

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PhysicalAddress

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

Formats the value using the given formatter.

impl Default for PhysicalAddress

fn default() -> PhysicalAddress

Returns the “default value” for a type.

impl Display for PhysicalAddress

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

Formats the value using the given formatter.

impl<S> From<PhysicalPage<S>> for PhysicalAddress

where S: PageSize,

fn from(value: PhysicalPage<S>) -> Self

Converts to this type from the input type.

impl From<u64> for PhysicalAddress

fn from(v: u64) -> Self

impl Ord for PhysicalAddress

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

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

Tests greater than (for self and other) and is used by the > operator.

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