High-level resource description for texture and surface objects.

Converted to CUDA_RESOURCE_DESC when creating a CudaTextureObject or CudaSurfaceObject.

Variants

Array

A CUDA array resource (most common for textures and surfaces).

Fields

handle: CUarray

Raw array handle.

MipmappedArray

A mipmapped CUDA array resource.

Fields

handle: CUmipmappedArray

Raw mipmapped array handle.

Linear

Linear device-memory resource (no filtering beyond point).

Fields

dev_ptr: DevicePtr

Device pointer to the linear region.

format: ArrayFormat

Channel element format.

num_channels: u32

Number of channels.

size_in_bytes: usize

Total size in bytes.

Pitch2d

Pitched 2-D device-memory resource.

Fields

dev_ptr: DevicePtr

Device pointer to the first row.

format: ArrayFormat

Channel element format.

num_channels: u32

Number of channels.

width_in_elements: usize

Width of the region in elements.

height: usize

Height of the region in elements.

pitch_in_bytes: usize

Row pitch in bytes.

Implementations
