Implementations

impl ArrayObject

pub fn from_descriptor(descriptor: &ArrayDescriptor) -> CudaResult<Self>

Constructs a generic ArrayObject from an ArrayDescriptor.

pub fn new( dims: [usize; 3], format: ArrayFormat, num_channels: c_uint, ) -> CudaResult<Self>

Allocates a new CUDA Array that is up to 3-dimensions.

dims contains the extents of the array. dims[0] must be non-zero. dims[1] must be non-zero if dims[2] is non-zero. The rank of the array is equal to the number of non-zero dims.

format determines the data-type of the array.

num_channels determines the number of channels per array element (1, 2, or 4).

use rustacuda::memory::array::{ArrayObject, ArrayFormat};

let one_dim_array = ArrayObject::new([10, 0, 0], ArrayFormat::Float, 1)?;
let two_dim_array = ArrayObject::new([10, 12, 0], ArrayFormat::Float, 1)?;
let three_dim_array = ArrayObject::new([10, 12, 14], ArrayFormat::Float, 1)?;

pub fn new_1d( width: usize, format: ArrayFormat, num_channels: c_uint, ) -> CudaResult<Self>

Allocates a new 1D CUDA Array.

width must be non-zero.

format determines the data-type of the array.

num_channels determines the number of channels per array element (1, 2, or 4).

use rustacuda::memory::array::{ArrayObject, ArrayFormat};

// Allocates a 1D array of 10 single-precision, single-channel floating point values.
let one_dim_array = ArrayObject::new_1d(10, ArrayFormat::Float, 1)?;

pub fn new_2d( dims: [usize; 2], format: ArrayFormat, num_channels: c_uint, ) -> CudaResult<Self>

Allocates a new CUDA Array that is up to 2-dimensions.

dims contains the extents of the array. dims[0] must be non-zero. The rank of the array is equal to the number of non-zero dims.

format determines the data-type of the array.

num_channels determines the number of channels per array element (1, 2, or 4).

use rustacuda::memory::array::{ArrayObject, ArrayFormat};

// Allocates an 8x24 array of single-precision, single-channel floating point values.
let one_dim_array = ArrayObject::new_2d([8, 24], ArrayFormat::Float, 1)?;

pub fn new_layered( dims: [usize; 2], num_layers: usize, format: ArrayFormat, num_channels: c_uint, ) -> CudaResult<Self>

Creates a new Layered 1D or 2D CUDA Array.

dims contains the extents of the array. dims[0] must be non-zero. The rank of the array is equivalent to the number of non-zero dimensions.

num_layers determines the number of layers in the array.

format determines the data-type of the array.

num_channels determines the number of channels per array element (1, 2, or 4).

use rustacuda::memory::array::{ArrayObject, ArrayFormat};

// Allocates a 7x8 array with 10 layers of single-precision, single-channel floating
// point values.
let layered_array = ArrayObject::new_layered([7, 8], 10, ArrayFormat::Float, 1)?;

pub fn new_layered_1d( width: usize, num_layers: usize, format: ArrayFormat, num_channels: c_uint, ) -> CudaResult<Self>

Creates a new Layered 1D CUDA Array.

width must be non-zero.

num_layers determines the number of layers in the array.

format determines the data-type of the array.

num_channels determines the number of channels per array element (1, 2, or 4).

use rustacuda::memory::array::{ArrayObject, ArrayFormat};

// Allocates a 5-element array with 10 layers of single-precision, single-channel floating
// point values.
let layered_array = ArrayObject::new_layered_1d(5, 10, ArrayFormat::Float, 1)?;

pub fn new_cubemap( side: usize, format: ArrayFormat, num_channels: c_uint, ) -> CudaResult<Self>

Creates a new Cubemap CUDA Array. The array is represented as 6 side x side 2D arrays.

side is the length of an edge of the cube.

format determines the data-type of the array.

num_channels determines the number of channels per array element (1, 2, or 4).

use rustacuda::memory::array::{ArrayObject, ArrayFormat};

// Allocates an 8x8 Cubemap array of single-precision, single-channel floating point
// numbers.
let layered_array = ArrayObject::new_cubemap(8, ArrayFormat::Float, 1)?;

// All non-layered cubemap arrays have a depth of 6.
assert_eq!(6, layered_array.descriptor()?.depth());

pub fn new_layered_cubemap( side: usize, num_layers: usize, format: ArrayFormat, num_channels: c_uint, ) -> CudaResult<Self>

Creates a new Layered Cubemap CUDA Array. The array is represented as multiple 6 side x side 2D arrays.

side is the length of an edge of the cube.

num_layers is the number of cubemaps in the array. The actual “depth” of the array is num_layers * 6.

format determines the data-type of the array.

num_channels determines the number of channels per array element (1, 2, or 4).

use rustacuda::memory::array::{ArrayObject, ArrayFormat};

// Allocates an 8x8 Layered Cubemap array of single-precision, single-channel floating point
// values with 5 layers.
let layered_array = ArrayObject::new_layered_cubemap(8, 5, ArrayFormat::Float, 1)?;

// The depth of a layered cubemap array is equal to the number of layers * 6.
assert_eq!(30, layered_array.descriptor()?.depth());

pub fn descriptor(&self) -> CudaResult<ArrayDescriptor>

Gets the descriptor associated with this array.

pub fn drop(array: ArrayObject) -> DropResult<ArrayObject>

Try to destroy an ArrayObject. Can fail - if it does, returns the CUDA error and the un-destroyed array object
