Struct DmaMapHandle 

pub struct DmaMapHandle { /* private fields */ }

Implementations

impl DmaMapHandle

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

Safety

cpu_addr must point to the caller-owned mapped buffer for the mapping lifetime. bounce_ptr, when present, must point to a live bounce buffer described by layout.

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

pub fn bounce_ptr(&self) -> Option<NonNull<u8>>

Trait Implementations

impl Clone for DmaMapHandle

fn clone(&self) -> DmaMapHandle

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DmaMapHandle

impl Debug for DmaMapHandle

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

Formats the value using the given formatter.

impl Eq for DmaMapHandle

impl Hash for DmaMapHandle

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 DmaMapHandle

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