[jira] [Created] (ARROW-11848) [Rust] Expose SlicesIterator from filter kernel?

Ben Chambers created ARROW-11848:
------------------------------------

             Summary: [Rust] Expose SlicesIterator from filter kernel?
                 Key: ARROW-11848
                 URL: https://issues.apache.org/jira/browse/ARROW-11848
             Project: Apache Arrow
          Issue Type: Task
          Components: Rust
            Reporter: Ben Chambers


I have found this iterator useful for some special purpose kernels I've created. For instance, I created something for concatenating multiple arrays together and "spreading them out", such that "filter(spread(input, bits), bits) == input".

While some of these special kernels could be added to Arrow, it seems like exposing the building-blocks could be useful too. Thoughts?
