Re: [I] Option to implement `std::convert::AsRef` for `Field`? [arrow-rs]

   I tried to workaround lack of `AsRef` provided by `Field`.
   Of course, rust won't allow me to just add `impl AsRef<Field> for Field` in downstream project, so I tried to get away with my own trait as a replacement for `AsRef`
   
   ```rust
   // workaround for the fact that Field does not implement AsRef<Field>
   trait AsFieldRef {
       fn as_ref(&self) -> &Field;
   }
   
   impl AsFieldRef for Field {
       fn as_ref(&self) -> &Field {
           self
       }
   }
   
   impl<T> AsFieldRef for T
   where
       T: AsRef<Field>,
   {
       fn as_ref(&self) -> &Field {
           self.as_ref()
       }
   }
   ```
   
   Unfortunately, this won't work either. Rust reports duplicate implementation because upstream may add `impl AsRef<Field> for Field` in the future.
