### Is your feature request related to a problem or challenge? I'm revamping the planner in Comet for some recent changes happened in DataFusion, especially for scalar functions. I found that a few built-in scalar functions are moved into module `expr_fn` with the approach with some macros. One trouble with this approach is it is hard to trace how does these functions are used across DataFusion. At least in RustRover IDE, it cannot trace the function usage on these function defined by `export_functions` macro. I'm not sure how do other deal with it? ### Describe the solution you'd like _No response_ ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
