   make sense to me.
   
   >Since what "semantically compatible" means may be pretty specific to each 
use case, I am not sure how much value moving the code to arrow-rs would bring 
   
   I was thinking of introducing an enum/struct that would serve as a gauge for 
how in-depth the comparison would be:
   
   ```
   struct EquivalenceGauge {
       check_nullability: bool,
       check_field_name: bool,
       check_metadata: bool,
   }
   ```
   
   `fn compare_datatype(dt_1: &DataType, dt_2: &DataType, eq: EquivalenceGauge) 
-> bool`
   
   decided to go with a struct since it allows us to update this in the future 
without making it a breaking api change
