Struct RegisterFlags 

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

Bitflags controlling how cuMemHostRegister registers host memory.

Implementations

impl RegisterFlags

pub const PORTABLE: Self

Memory is portable across CUDA contexts.

pub const DEVICE_MAP: Self

Memory is mapped into the device address space, enabling zero-copy access via cuMemHostGetDevicePointer.

pub const IO_MEMORY: Self

Pointer refers to I/O memory (not system RAM).

pub const READ_ONLY: Self

Memory will not be written by the GPU (read-only hint).

pub const DEFAULT: Self

The recommended default: portable + device-mapped.

pub const NONE: Self

No flags set.

pub const fn bits(self) -> u32

Returns the raw u32 flag value.

pub const fn from_bits(bits: u32) -> Self

Creates a RegisterFlags from a raw u32 value.

pub const fn contains(self, other: Self) -> bool

Returns true if self contains all flags in other.

Trait Implementations

impl BitAnd for RegisterFlags

type Output = RegisterFlags

The resulting type after applying the & operator.

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

Performs the & operation.

impl BitOr for RegisterFlags

type Output = RegisterFlags

The resulting type after applying the | operator.

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

Performs the | operation.

impl Clone for RegisterFlags

fn clone(&self) -> RegisterFlags

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RegisterFlags

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

Formats the value using the given formatter.

impl Display for RegisterFlags

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

Formats the value using the given formatter.

impl Hash for RegisterFlags

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 RegisterFlags

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