URL: https://github.com/apache/arrow-rs/issues/1038


   **Is your feature request related to a problem or challenge? Please describe what you are trying to do.**
   
   `BooleanBufferBuilder` currently has no mechanism to append an already packed bitmask, instead requiring bitwise iteration through the mask. This is particularly wasteful where the `BooleanBufferBuilder` has a length that is a multiple of 8, where a simple memcpy would suffice. I ran into this limitation whilst working on #1037
   
   **Describe the solution you'd like**
   
   In IOx we have a BitSet implementation that allows directly appending a bitmask - see [here](https://github.com/influxdata/influxdb_iox/blob/fe0bc2180732cc2189cbfe9a4727294793d25f4d/arrow_util/src/bitset.rs#L111). This logic could pretty much just be copied and pasted into arrow.
