### Describe the bug I'm looking for a way to pass down the input field into my UDAF, as I need the field metadata to access the Arrow extension metadata. It looks like [`AccumulatorArgs.schema`](https://docs.rs/datafusion/latest/datafusion/logical_expr/function/struct.AccumulatorArgs.html#structfield.schema) is the intended way to do this, but this is empty for scalar input. ### To Reproduce ``` git clone https://github.com/geoarrow/geoarrow-rs cd geoarrow-rs git checkout 3e45aa368715ccff7ba0a6f76abd11539ba548b3 cargo test -p geodatafusion udf::native::bounding_box::extent::test::test -- --nocapture ``` This tests the following SQL: ```sql select ST_Extent(ST_GeomFromText('POLYGON((743238 2967416,743238 2967450, 743265 2967450,743265.625 2967416,743238 2967416))')); ``` You can see ``` [rust/geodatafusion/src/udf/native/bounding_box/extent.rs:63:9] &acc_args.schema = Schema { fields: [], metadata: {}, } ``` where the `Schema` passed in to the accumulator is empty. I figure that here the `Schema` is supposed to be non-empty with the correct input field types. ### Expected behavior `Schema` should include the input fields from the scalar input. ### Additional context cc @timsaucer as you asked to let you know if I hit any other bugs with extension types. -- This is an automated message from the Apache Git Service.
