@milesgranger My guess is you will want to instantiate an `ExtensionArray` from a 'regular' `Array` by passing the underlaying buffers, kind of like what [CastFromExtension](https://github.com/apache/arrow/blob/master/cpp/src/arrow/compute/kernels/scalar_cast_internal.cc#L152-L163) does and then add c++ test like [this one](https://github.com/apache/arrow/blob/6cc37cf2d1ba72c46b64fbc7ac499bd0d7296d20/cpp/src/arrow/compute/kernels/scalar_cast_test.cc#L2731-L2766). -- This is an automated message from the Apache Git Service.
