I'm looking at fixing up support for NumPy record arrays in Cython, and
realize my knowledge of NumPy is a bit too limited. Searching the docs
didn't enlighten me, so:
Does NumPy always use packed alignment for nested dtypes?
In [35]: T
Out[35]: dtype([('f0', '<f4'), ('f1', '|i1'), ('f2', '<i4')])
In [36]: T.itemsize
Out[36]: 9
In [37]: T.alignment
Out[37]: 1
In [48]: np.zeros(3,T).itemsize
Out[48]: 9
Is there a way of making an array with the above dtype but 12 bytes per
element? Or can you guarantee that NumPy arrays with records are always
packed?
