Struct cudaPointerAttributes 

#[repr(C)]
pub struct cudaPointerAttributes {
    pub type_: cudaMemoryType,

CUDA pointer attributes.

Fields

type_: cudaMemoryType

device: c_int

The device against which the memory was allocated or registered. If the memory type is cudaMemoryType::cudaMemoryTypeDevice then this identifies the device on which the memory referred physically resides. If the memory type is cudaMemoryType::cudaMemoryTypeHost then this identifies the device which was current when the memory was allocated or registered (and if that device is deinitialized then this allocation will vanish with that device’s state).

devicePointer: *mut c_void

The address which may be dereferenced on the current device to access the memory or NULL if no such address exists.

hostPointer: *mut c_void

The address which may be dereferenced on the host to access the memory or NULL if no such address exists.

Note:

CUDA doesn't check if unregistered memory is allocated so this field may contain invalid pointer if an invalid pointer has
been passed to CUDA.

reserved: [c_long; 8]

Must be zero.

Trait Implementations

impl Clone for cudaPointerAttributes

fn clone(&self) -> cudaPointerAttributes

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for cudaPointerAttributes

impl Debug for cudaPointerAttributes

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

Formats the value using the given formatter.

impl Default for cudaPointerAttributes

fn default() -> Self

Returns the “default value” for a type.

impl Eq for cudaPointerAttributes

impl Hash for cudaPointerAttributes

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 Ord for cudaPointerAttributes

fn cmp(&self, other: &cudaPointerAttributes) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for cudaPointerAttributes

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

impl PartialOrd for cudaPointerAttributes

fn partial_cmp(&self, other: &cudaPointerAttributes) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
