This request has come up again on https://github.com/apache/arrow-rs/issues/7119#issuecomment-2654025232 I think adding a function along the lines of (possibly with Result and some error handling) ``` pub fn mask(a: &dyn Array, mask: &BooleanBuffer) -> ArrayRef { let nulls = a.nulls().clone(); let builder = a.to_data().into_builder(); let builder = match nulls { None => builder.nulls(Some(mask.clone().into())), Some(nulls) => builder.nulls((mask & nulls.inner()).into()) }; make_array(unsafe {builder.build_unchecked()}) } ``` Would be a valuable addition -- This is an automated message from the Apache Git Service.
