Struct Array 

pub struct Array { /* private fields */ }

A 2-D / 3-D CUDA array handle.

Implementations

impl Array

pub fn new_2d( desc: &cudaChannelFormatDesc, width: usize, height: usize, flags: u32, ) -> Result<Self>

Allocate a 2-D array width × height with the given channel descriptor. flags = 0 for the default layout.

pub fn new_3d( desc: &cudaChannelFormatDesc, extent: cudaExtent, flags: u32, ) -> Result<Self>

Allocate a 3-D array with the given extent + descriptor. flags = 0 for the default.

pub unsafe fn from_raw( handle: cudaArray_t, desc: cudaChannelFormatDesc, width: usize, height: usize, depth: usize, ) -> Self

Wrap an already-allocated cudaArray_t.

Safety

handle must be a live CUDA array. The wrapper frees it on drop.

pub fn as_raw(&self) -> cudaArray_t

Raw cudaArray_t handle. Use with care — owned by self.

pub fn width(&self) -> usize

Width of the array, in elements.

pub fn height(&self) -> usize

Height of the array, in elements. Zero for a 1-D array.

pub fn depth(&self) -> usize

Depth of the array, in elements. Zero for a 1- or 2-D array.

pub fn desc(&self) -> &cudaChannelFormatDesc

The channel-format descriptor captured at allocation time.

pub fn info(&self) -> Result<(cudaChannelFormatDesc, cudaExtent, u32)>

Query the runtime-reported channel desc + extent.

Trait Implementations

impl Clone for Array

fn clone(&self) -> Array

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Array

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

Formats the value using the given formatter.
