----------------------------------------------------------------
Before this, do we need to first add struct type support to the `pa.array`
factory function? Currently it doesn't seem supported:
{code}
>>> ty = pa.struct([pa.field('key', pa.int32()), pa.field('value',
>>> pa.float64())])
>>> pa.array([[1, 2], [3, 4]], type=ty)
Traceback (most recent call last):
File "<ipython-input-29-f5e8f7daa504>", line 1, in <module>
pa.array([[1, 2], [3, 4]], type=ty)
File "array.pxi", line 174, in pyarrow.lib.array
File "array.pxi", line 29, in pyarrow.lib._sequence_to_array
File "error.pxi", line 85, in pyarrow.lib.check_status
ArrowNotImplementedError: No type converter implemented for struct<key: int32,
value: double>
