[GitHub] [arrow-datafusion] crepererum commented on issue #6677: `Debug` impl `Expr` is lossy

   @parkma99 I think you have to fix the Rust code to not use `Debug` but `Display` for for the plan printers (`fmt_as`):
   
   - `SortMergeJoin`
   - `SortExec`
   - `RepartitionExec`
   - `ProjectionExec`
   
   Here is one example fix:
   
   https://github.com/apache/arrow-datafusion/blob/d29ab931506f23d8ef8fcd48ae523adfd3c07d6a/datafusion/core/src/physical_plan/repartition/mod.rs#L447-L462
   
   `partitioning={:?}` should be `partitioning={}`. However `Partitioning` doesn't implement `Display` yet, so you probably wanna hand-roll that.
   
   Similar fixes are required for the other exec nodes.
