paleolimbot opened a new pull request, #208: URL: https://github.com/apache/arrow-nanoarrow/pull/208
After #207, buffer data types are readily available. Before, the R bindings did most of this on their own to get debug buffer printing. This PR exploits the new feature to improve debug output and adds the ability to convert buffers into R vectors along the way.
