All good! I don't have an example for that pattern yet in examples/ but there's a test that does that: https://github.com/apache/arrow-nanoarrow/blob/main/src/nanoarrow/array_test.cc#L182-L231 If you want/need to avoid the `memcpy()`, the "deallocator" pattern may be helpful. I haven't used it yet in anything except dinky tests but the idea is to use it in the R package to avoid copying vectors (just like narrow did): https://github.com/apache/arrow-nanoarrow/blob/main/src/nanoarrow/utils_test.cc#L104-L127 > nanoarrow as a lighterweight replacement for Arrow in the creation steps of some data pipelines.
