   Hi, really cool stuff. I use dtolnay/inventory on my project, but it has a known issue where one cannot guarantee that symbols won't get mangled from statically compiled code by llvm. Stuff got stirred and the core team reacted https://github.com/rust-lang/rust/issues/47384 but it's not solved yet. 
   Can we guarantee here that statically compiled plugins won't end up forgotten in binaries ?
   
   Secondly, I think it'd be cool to implement your interface in datafusion python so that people can use a python function as a UDAF like it's done in pyspark https://spark.apache.org/docs/2.4.0/sql-pyspark-pandas-with-arrow.html#pandas-udfs-aka-vectorized-udfs
