Function malloc_pitch 

pub fn malloc_pitch(
    width_bytes: usize,
    height: usize,
) -> CudaRtResult<(DevicePtr, usize)>

Allocate pitched device memory for 2-D arrays.

Mirrors cudaMallocPitch.

Returns (device_ptr, pitch_bytes). pitch_bytes is ≥ width_bytes and aligned to the hardware’s texture alignment.
