Descriptor for a 2-D memory copy executed via cuMemcpy2D_v2.

Mirrors CUDA_MEMCPY2D in cuda.h. The CUDA driver inspects only the fields appropriate for the source / destination memory types; the remaining fields must be zeroed. Use CUDA_MEMCPY2D::default to obtain a zero-initialised descriptor and only set the fields you need.

src_memory_type and dst_memory_type are stored as raw u32 for FFI safety; convert to / from CUmemorytype manually.

Fields

src_x_in_bytes: usize

Source X offset in bytes.

src_y: usize

Source Y offset in rows.

src_memory_type: u32

Source memory type; see CUmemorytype.

src_host: *const c_void

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

src_device: CUdeviceptr

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

src_array: CUarray

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

src_pitch: usize

Source pitch in bytes (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_memory_type: u32

Destination memory type; see CUmemorytype.

dst_host: *mut c_void

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

dst_device: CUdeviceptr

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

dst_array: CUarray

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

dst_pitch: usize

Destination pitch in bytes (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.
