Struct PhysFrame 

pub struct PhysFrame<H: AxMmHal> { /* private fields */ }

A physical frame which will be automatically deallocated when dropped.

The frame is allocated using the AxMmHal implementation. The size of the frame is likely to be 4 KiB but the actual size is determined by the AxMmHal implementation.

Implementations

impl<H: AxMmHal> PhysFrame<H>

pub fn alloc() -> AxResult<Self>

Allocate a PhysFrame.

pub fn alloc_zero() -> AxResult<Self>

Allocate a PhysFrame and fill it with zeros.

pub const unsafe fn uninit() -> Self

Create an uninitialized PhysFrame.

Safety

The caller must ensure that the PhysFrame is only used as a placeholder and never accessed.

pub fn start_paddr(&self) -> HostPhysAddr

Get the starting physical address of the frame.

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

Get a mutable pointer to the frame.

pub fn fill(&mut self, byte: u8)

Fill the frame with a byte. Works only when the frame is 4 KiB in size.

Trait Implementations

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

Formats the value using the given formatter.

impl<H: AxMmHal> Drop for PhysFrame<H>

fn drop(&mut self)

Executes the destructor for this type.
