In Python 3.11 the _PyFrameEvalFunction receives a _PyInterpreterFrame opaque struct.

Python 3.11.0 (alpha 7) changelog:

...
bpo-46850: Move the private _PyFrameEvalFunction type, and private _PyInterpreterState_GetEvalFrameFunc() and _PyInterpreterState_SetEvalFrameFunc() functions to the internal C API. The _PyFrameEvalFunction callback function type now uses the _PyInterpreterFrame type which is part of the internal C API. Patch by Victor Stinner.
bpo-46850: Move the private undocumented _PyEval_EvalFrameDefault() function to the internal C API. The function now uses the _PyInterpreterFrame type which is part of the internal C API. Patch by Victor Stinner.

Thanks! Don't worry about the CI failures; you'll need to rebase once #3498 lands.

It looks like (at least on CPython main) that this symbol resides in cpython/pyframe.h. Can you please create the corresponding .rs file and place this there?

Is this available in PyPy? I couldn't find anything about it.

I couldn't find it either 😅

I've added #[cfg(not(PyPy))] to the pub(crate) mod pyframe; line on src/cpython/mod.rs because PyPy does not have something like "pyframe.h" in their source code.
