[GitHub] [arrow-rs] tustvold opened a new issue, #1978: PrimitiveBuilder::finish_dict does not validate dictionary offsets

tustvold opened a new issue, #1978:
URL: https://github.com/apache/arrow-rs/issues/1978

   **Describe the bug**
   
   PrimitiveBuilder::finish_dict does not validate that the provided values array contains enough values for the largest key in the dictionary
   
   **To Reproduce**
   
   ```
   #[test]
   fn test_primitive_array_builder_dict() {
       let mut builder = Int32Array::builder(10);
       builder.append_value(1).unwrap();
   
       let values = Arc::new(Int32Array::from_iter_values([0]));
       let dict = builder.finish_dict(values);
   }
   ```
   
   **Expected behavior**
   
   It should not be possible to construct invalid ArrayData with safe APIs
