Struct kernel::dma::Attrs

pub struct Attrs(/* private fields */);

Possible attributes associated with a DMA mapping.

They can be combined with the operators |, &, and !.

Values can be used from the attrs module.

Examples

use kernel::device::Device;
use kernel::dma::{attrs::*, CoherentAllocation};

let attribs = DMA_ATTR_FORCE_CONTIGUOUS | DMA_ATTR_NO_WARN;
let c: CoherentAllocation<u64> =
    CoherentAllocation::alloc_attrs(dev, 4, GFP_KERNEL, attribs)?;

Implementations

impl Attrs

pub fn contains(self, flags: Attrs) -> bool

Check whether flags is contained in self.

Trait Implementations

impl BitAnd for Attrs

type Output = Attrs

The resulting type after applying the & operator.

fn bitand(self, rhs: Self) -> Self::Output

Performs the & operation.

impl BitOr for Attrs

type Output = Attrs

The resulting type after applying the | operator.

fn bitor(self, rhs: Self) -> Self::Output

Performs the | operation.

impl Clone for Attrs

fn clone(&self) -> Attrs

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Not for Attrs

type Output = Attrs

The resulting type after applying the ! operator.

fn not(self) -> Self::Output

Performs the unary ! operation.

impl PartialEq for Attrs

fn eq(&self, other: &Attrs) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
