**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** I have a need to create array builders for many different types and then add some number of nulls to them. I noticed that only some builder types support `append_nulls`. **Describe the solution you'd like** I'd like it if there was an efficient way to add many nulls to my builder. Some builders expose an `add_nulls` method (like [BooleanBulder](https://docs.rs/arrow/latest/arrow/array/struct.BooleanBuilder.html#method.append_nulls) for example), while others do not, including: - FixedSizeBinaryDictionaryBuilder - FixedSizedBinaryBuilder - GenericBytesBuilder - GenericListBuilder - StructBuilder **Describe alternatives you've considered** call `append_null` many times. ```rs for _ in 0..n { builder.append_null(); } ``` **Additional context** <!-- Add any other context or screenshots about the feature request here. --> -- This is an automated message from the Apache Git Service.
