}

Descriptor for a 3-D memory copy, consumed by cuGraphAddMemcpyNode (and cuMemcpy3D).

Mirrors CUDA_MEMCPY3D in cuda.h. The driver inspects only the fields appropriate for the chosen source / destination memory types; the rest must be zeroed. Use CUDA_MEMCPY3D::default to obtain a zero-initialised descriptor and set only the fields you need.

Fields

src_x_in_bytes: usize

Source X offset in bytes.

src_y: usize

Source Y offset in rows.

src_z: usize

Source Z offset in slices.

src_lod: usize

Source LOD (level of detail).

src_memory_type: u32

Source memory type; see super::CUmemorytype.

src_host: *const c_void

Source host pointer (valid when src_memory_type == Host).

src_device: CUdeviceptr

Source device pointer (valid when src_memory_type == Device).

src_array: CUarray

Source CUDA array (valid when src_memory_type == Array).

reserved0: *mut c_void

Reserved; must be null.

src_pitch: usize

Source pitch in bytes (0 selects a tightly-packed layout).

src_height: usize

Source height in rows (0 selects a tightly-packed layout).

dst_x_in_bytes: usize

Destination X offset in bytes.

dst_y: usize

Destination Y offset in rows.

dst_z: usize

Destination Z offset in slices.

dst_lod: usize

Destination LOD (level of detail).

dst_memory_type: u32

Destination memory type; see super::CUmemorytype.

dst_host: *mut c_void

Destination host pointer (valid when dst_memory_type == Host).

dst_device: CUdeviceptr

Destination device pointer (valid when dst_memory_type == Device).

dst_array: CUarray

Destination CUDA array (valid when dst_memory_type == Array).

reserved1: *mut c_void

Reserved; must be null.

dst_pitch: usize

Destination pitch in bytes (0 selects a tightly-packed layout).

dst_height: usize

Destination height in rows (0 selects a tightly-packed layout).

width_in_bytes: usize

Width of the copied region in bytes.

height: usize

Height of the copied region in rows.

depth: usize

Depth of the copied region in slices.
