vertexclique opened a new pull request #8598:
URL: https://github.com/apache/arrow/pull/8598
Currently, bit slice, bit view, and operations all kind of bit operations
looking blurry.
- Support native endianness
- Fix problems related to bit operations
- Method docs are written.
- Separate view and bit operation
- Have good benchmarks still
