AlenkaF opened a new pull request #11765:
URL: https://github.com/apache/arrow/pull/11765
In this PR I added `StructFieldOptions` binding and two small typo
corrections for `TypeError` message in `compute.py`.
What I haven't managed to solve and would ask for suggestions is the case
when options are not specified. Example:
```python
import pyarrow as pa
import pyarrow.compute as pc
a = pa.array([4, 5, 6], type=pa.int64())
b = pa.array(["bar", None, ""])
c = pa.StructArray.from_arrays([a, b], ["a", "b"])
arr = pa.StructArray.from_arrays([a, c], ["a", "c"])
pc.struct_field(arr)
```
This error I get:
```python-traceback
>>> pc.struct_field(arr)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/Users/alenkafrim/repos/arrow/python/pyarrow/compute.py", line 202,

File "pyarrow/error.pxi", line 99, in pyarrow.lib.check_status
raise ArrowInvalid(message)

For which I tried to add
https://github.com/AlenkaF/arrow/blob/bec0a6beac3415e03400088a3269f3be3fc7150c/python/pyarrow/_compute.pyx#L977-L978
but it doesn't seem to help.
