Struct DmaAllocHandle 

pub struct DmaAllocHandle { /* private fields */ }

Implementations

impl DmaAllocHandle

pub unsafe fn new( cpu_addr: NonNull<u8>, dma_addr: DmaAddr, layout: Layout, ) -> Self

Safety

cpu_addr must point to a live allocation described by layout, and dma_addr must be the device-visible address for that allocation.

pub fn size(&self) -> usize

pub fn align(&self) -> usize

pub fn as_ptr(&self) -> NonNull<u8>

pub fn dma_addr(&self) -> DmaAddr

pub fn layout(&self) -> Layout

Trait Implementations

impl Clone for DmaAllocHandle

fn clone(&self) -> DmaAllocHandle

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DmaAllocHandle

impl Debug for DmaAllocHandle

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

Formats the value using the given formatter.

impl Eq for DmaAllocHandle

impl Hash for DmaAllocHandle

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 PartialEq for DmaAllocHandle

fn eq(&self, other: &DmaAllocHandle) -> 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.
