Struct PhysAddr 

pub struct PhysAddr(/* private fields */);

CPU-visible physical address of RAM (SDRAM, SRAM, etc.).

Distinct from DmaAddr and MmioAddr<T> so that a value intended as a framebuffer origin cannot be silently assigned to a DMA source or a register-block base.

Implementations

impl PhysAddr

pub const fn new(addr: u32) -> Self

Construct a PhysAddr from a raw 32-bit address.

pub const fn raw(self) -> u32

Raw 32-bit address.

pub const fn offset(self, delta: u32) -> Self

Offset this address by delta bytes, returning a new PhysAddr.

Saturating on overflow. No aliasing, MMU, or mapping check is performed — callers stay responsible for validity.

pub const fn sdram_bank(self) -> Option<u8>

SDRAM bank index (0..SDRAM_BANK_COUNT) for Bank-2-based SDRAM, or None if this address is not inside the SDRAM Bank 2 window.

Replaces the inline (addr - 0xD000_0000) / SDRAM_BANK_STRIDE expression that framebuffer collision detection previously used.

pub unsafe fn as_mut_slice<'a>(self, len: usize) -> &'a mut [u8]

Reconstruct a mutable byte slice spanning len bytes starting at this address.

Safety

The caller must ensure that:

• the region [self, self+len) is mapped and writable for 'a,
• no other &_ or &mut _ to any overlapping bytes exists for 'a,
• the region is not concurrently written by a DMA master (see DmaAddr and the InFlight<T> handoff pattern).

Trait Implementations

impl Clone for PhysAddr

fn clone(&self) -> PhysAddr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for PhysAddr

impl Debug for PhysAddr

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

Formats the value using the given formatter.

impl Eq for PhysAddr

impl Hash for PhysAddr

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for PhysAddr

fn cmp(&self, other: &PhysAddr) -> 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,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for PhysAddr

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for PhysAddr

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

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