Struct DeviceArrayView 

pub struct DeviceArrayView<'a, T: CugraphElement> { /* private fields */ }

A non-owning view into device (GPU) memory with compile-time element type T.

The lifetime parameter 'a ties this view to whatever owns the underlying memory (a DeviceArray, a result object, etc.), preventing use-after-free.

Implementations

impl<'a, T: CugraphElement> DeviceArrayView<'a, T>

pub fn device_ptr(&self) -> *mut c_void

Device pointer to the first element of this view.

pub fn len(&self) -> usize

Number of elements in this view.

pub fn is_empty(&self) -> bool

Whether this view is empty.

pub fn to_vec(&self, handle: &EnteredContext<'_>) -> Result<Vec<T>>

Copy device array data to a typed host vector.

Example

let arr = DeviceArray::from_slice(&entered, &[10i32, 20, 30]).unwrap();
let values: Vec<i32> = arr.view().unwrap().to_vec(&entered).unwrap();
assert_eq!(values, vec![10, 20, 30]);

Trait Implementations

impl<T: CugraphElement> Debug for DeviceArrayView<'_, T>

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

Formats the value using the given formatter.

impl<'a, V: CugraphElement> From<&'a DeviceArrayView<'a, V>> for VertexSelection<'a, V>

fn from(view: &'a DeviceArrayView<'a, V>) -> Self

Converts to this type from the input type.
