Description
Proposed new feature or change:
Following this issue #11161 and related PR, can we support no-copy pickling for recarray, which is a subclass of ndarray? I think right now we don't support this feature, since recarray is non-contiguous arrays.
If it's possible in your experienced view, I guess we need to do some changes in numpy/core/src/multiarray/methods.c and related tests.
Example is here: ray-project/ray#37573 (comment). I can make up a version without Ray later.
And I saw a demo for how to handle pd DataFrame #12011 (comment), don't know if we can have a local trick for recarray too.
