C isn't really the protocol though, its just a way every language has of exporting simple symbols. Otherwise how else does this work, you'd never every language to understand every other languages symbol name encoding scheme, some of which are complete jibberish (I'm looking hard your way C++).

The real protocol in action here is symbolic linking and hardware call ABIs.

You could always directly call Rust functions, but you'd have to know where to symbolically look for them and how to craft its parameters for example.

If this is well defined then its possible. If its poorly defined or implementation specific (c++) then yeah its a shit show that is not solvable.
