> The minmax compute function returns a struct with fields "min" and "max". So
> to write an R binding for the {{min()}} method on arrow objects, I call
> "minmax" and then take the "min" field from the result. However, at least
> from my reading of scalar.h compared with array_nested.h, there are no
> field/GetFieldByName/etc. methods for StructScalar, so I can't get it.
