**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** DataFusion handles structured types specially in some cases. It would be nice to have a function in `DataType` to detect this case such as `DataType::is_nested` Ideally it would follow a similar model to https://docs.rs/arrow/22.0.0/arrow/datatypes/enum.DataType.html#method.is_numeric **Describe the solution you'd like** I would like a function like `DataType::is_nested()` or something similar that returns true for `FixedSizeList`, `LargeList`, etc. I think the list is: ```rust !matches!( field.data_type(), DataType::List(_) | DataType::FixedSizeList(_, _) | DataType::LargeList(_) | DataType::Struct(_) | DataType::Union(_, _, _) | DataType::Map(_, _) ) } ``` **Describe alternatives you've considered** <!-- A clear and concise description of any alternative solutions or features you've considered. --> **Additional context** See https://github.com/apache/arrow-datafusion/pull/3380/files#r967640804 -- This is an automated message from the Apache Git Service.
