Module dlpack 

DLPack interop for zero-copy GPU exchange.

This module provides a minimal DLPack implementation for exporting XLOG GPU buffers to other ecosystems (e.g., Python cuDF) without device↔host copies.

Structs

DLDataType

DLDevice

DLManagedTensor

DLTensor

DlpackManagedTensor

Owned DLPack tensor handle.

DlpackTable

A table-like wrapper that can export individual columns as DLPack tensors without copies.

Functions

export_slice_managed_tensor

Export an xlog-owned runtime-backed slice as a 2-D DLPack managed tensor without copies. The manager context holds the slice’s Arc, so the export shares the exact producer allocation and the memory stays alive until the consumer’s deleter runs; xlog remains the owner throughout. The declared rows x cols x dtype view must cover the allocation exactly — a mismatched shape is a typed error, never a truncated or padded view.
