   I think you want to use Arrow's C data interface. It's how we pass data between Python and R, to/from DuckDB in both Python and R, and how the Rust DataFusion project works with Python as well. 
   
   Some references:
   
   * reticulate methods in the arrow R package: https://github.com/apache/arrow/blob/master/r/R/python.R
   * implementation in arrow-rs: https://github.com/apache/arrow-rs/blob/master/arrow/src/ffi.rs
   * DataFusion's python library: https://github.com/datafusion-contrib/datafusion-python
   * Format docs: https://arrow.apache.org/docs/format/CDataInterface.html
