             Summary: [Rust] Build buffers from iterator of booleans
                 Key: ARROW-11361
                 URL: https://issues.apache.org/jira/browse/ARROW-11361
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Rust
            Reporter: Tyrel Rink
            Assignee: Tyrel Rink


Simplify the creation of bit buffers in the comparison kernel by introducing a 
standard Iterator<Item=bool> -> Buffer function.

Most null-buffer logic can rely on byte-level boolean operations, so it may not 
have much utility outside of the comparison kernel?
