pub struct PhysFrame { /* private fields */ }

Expand description

A 4K size physical frame.

Implementations

source

impl PhysFrame

source

pub fn new() -> Option<Self>

Allocate one physical frame.

source

pub fn new_zero() -> Option<Self>

Allocate one physical frame and fill with zero.

source

pub fn new_contiguous(frame_count: usize, align_log2: usize) -> Vec<Self>ⓘNotable traits for Vec<u8, A>`impl<A> Write for Vec<u8, A> where A: Allocator,`

Allocate contiguous physical frames.

source

pub unsafe fn from_paddr(paddr: PhysAddr) -> Self

Safety

This function is unsafe because the user must ensure that this is an available physical frame.

source

pub fn paddr(&self) -> PhysAddr

Get the start physical address of this frame.

source

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

convert to raw a pointer.

source

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

convert to a mutable raw pointer.

source

pub fn zero(&mut self)

Fill self with zero.
