Struct CarrierExport 

pub struct CarrierExport {
    pub slice: Arc<TrackedCudaSlice<u8>>,
    pub stream: Arc<CudaStream>,
    pub elem_bytes: usize,
    pub rows: usize,
    pub cols: usize,
}

One buffer exported outward while xlog retains ownership. The binding layer wraps slice in a real DLPack capsule via CudaColumn::dlpack_xlog_owned; the shared Arc keeps the runtime identity alive, so strict launch recorders keep recording the exported view instead of rejecting it.

Fields

slice: Arc<TrackedCudaSlice<u8>>

The runtime-backed allocation, shared with the carrier.

stream: Arc<CudaStream>

The stream the export synchronizes against.

elem_bytes: usize

Element width in bytes (8 for u64 buffers, 4 for u32/f32).

rows: usize

Logical row count of the 2-D view.

cols: usize

Logical column count of the 2-D view.
