URL: https://github.com/apache/arrow-rs/issues/1864
**Is your feature request related to a problem or challenge? Please describe
what you are trying to do.**
`filter::SlicesIterator` and `filter::IndexIterator` provide very efficient
mechanisms to iterate through validity buffers, in some cases yielding order of
magnitude improvements over element-wise iteration.
**Describe the solution you'd like**
Expose the following methods on `Bitmap` making use of these
```
fn iter_set_bits(&self, offset: usize) -> impl Iterator<usize> {}
fn iter_set_bit_ranges(&self, offset: usize) -> impl Iterator<(usize,
usize)> {}
```
**Describe alternatives you've considered**
We could not do this
**Additional context**
#1802 tracks extending Bitmap with the ability to track an offset
