Implementations

impl<T> Dma<T>

pub fn from_physbox_uninit(phys: PhysBox) -> Result<Dma<MaybeUninit<T>>>

pub fn from_physbox_zeroed(phys: PhysBox) -> Result<Dma<MaybeUninit<T>>>

pub fn from_physbox(phys: PhysBox, value: T) -> Result<Self>

pub fn new(value: T) -> Result<Self>

pub fn zeroed() -> Result<Dma<MaybeUninit<T>>>

impl<T> Dma<MaybeUninit<T>>

pub unsafe fn assume_init(self) -> Dma<T>

impl<T: ?Sized> Dma<T>

pub fn physical(&self) -> usize

pub fn size(&self) -> usize

pub fn phys(&self) -> &PhysBox

impl<T> Dma<[T]>

pub fn from_physbox_uninit_unsized(
    phys: PhysBox,
    len: usize
) -> Result<Dma<[MaybeUninit<T>]>>

pub fn from_physbox_zeroed_unsized(
    phys: PhysBox,
    len: usize
) -> Result<Dma<[MaybeUninit<T>]>>

pub unsafe fn zeroed_unsized(count: usize) -> Result<Self>

Creates a new DMA buffer with a size only known at runtime.

Safety

• T must be properly aligned.
• T must be valid as zeroed (i.e. no NonNull pointers).

impl<T> Dma<[MaybeUninit<T>]>

pub unsafe fn assume_init(self) -> Dma<[T]>

Trait Implementations

fn deref(&self) -> &T

Dereferences the value.

impl<T: ?Sized> DerefMut for Dma<T>

fn deref_mut(&mut self) -> &mut T

Mutably dereferences the value.

impl<T: ?Sized> Drop for Dma<T>

fn drop(&mut self)
