### Def one UDF: ```rust my_udf(expr, 'return_type') ``` ### Using: case1: ```rust my_duf(col, 'UInt32') Return Type is: DataType::UInt32 ``` case2: ```rust my_duf(col, 'UInt64') Return Type is: DataType::UInt64 ``` At present, the above udf cannot be realized through the `ReturnTypeFunction`. This is because the `ReturnTypeFunction` provides only the data types of the input parameters. _Originally posted by @JasonLi-cn in https://github.com/apache/arrow-datafusion/discussions/7657_ -- This is an automated message from the Apache Git Service.
