## Summary of Changes Hello @cyx-6, I'm Gemini Code Assist[^1]! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request exposes a new `get_raw_stream` method within the `tvm_ffi.stream` module, allowing users to retrieve the current FFI stream associated with a given device. This is achieved by adding a Cython binding (`_env_get_stream`) to an internal C++ function, defining the public Python API, and updating the module's `__init__.py`. New test assertions confirm the method's correct behavior, particularly within `use_raw_stream` contexts. ### Highlights * **Intent**: This pull request aims to expose a method to retrieve the current FFI stream for a given device, following up on a previous issue (#5). * **Changes Overview**: The PR introduces a new public function `get_raw_stream` in the `tvm_ffi.stream` module. This function allows users to query the currently active stream for a specified device. The implementation involves adding a Cython binding to an internal C++ function (`TVMFFIEnvGetStream`) and updating the `__init__.py` to expose the new method. Corresponding tests have been added to verify its functionality within stream contexts. * **File Changes**: The changes are distributed across four files: - `python/tvm_ffi/__init__.py`: Updated to import the newly exposed `get_raw_stream` function. - `python/tvm_ffi/cython/base.pxi`: A new Cython function `_env_get_stream` was added to provide a Python-callable wrapper for the internal `TVMFFIEnvGetStream` C++ function, enabling retrieval of the raw stream pointer. - `python/tvm_ffi/stream.py`: The public `get_raw_stream` function was defined, which takes a `tvm_ffi.Device` object and uses the new Cython binding to return the current stream as an integer. A comprehensive docstring was also added. - `tests/python/test_stream.py`: The `test_raw_stream` function was enhanced with assertions to confirm that `get_raw_stream` correctly reports the active stream when `use_raw_stream` context managers are used, including nested contexts. * **Reviewer Activity**: No specific reviewer activity or comments were provided in the context. <details> <summary><b>Using Gemini Code Assist</b></summary> <br> The full guide for Gemini Code Assist can be found on our [documentation page](https://developers.google.com/gemini-code-assist/docs/review-github-code), here are some quick tips. <b>Invoking Gemini</b> You can request assistance from Gemini at any point by creating a comment using either `/gemini <command>` or `@gemini-code-assist <command>`.
