class cuda.core.texture.OpaqueArrayOptions(

shape: tuple[int, ...],

format: object,

num_channels: int,

is_surface_load_store: bool = False,

)

Options for cuda.core.Device.create_opaque_array().

shape

(width,), (width, height), or (width, height, depth) in elements.

Type:

tuple of int

format

Element format. Accepts an ArrayFormatType, a plain string (e.g. "float32"), or a NumPy dtype object.

Type:

ArrayFormatType, str, or numpy.dtype

num_channels

Channels per element. Must be 1, 2, or 4.

Type:

int

is_surface_load_store

If True, allocate with CUDA_ARRAY3D_SURFACE_LDST so the array can be bound as a SurfaceObject for kernel-side writes. Default False.

Type:

bool
