Disclaimer: I have not used Rust myself.

The only API that we currently provide for writing plug-ins is based on 
C++. So - Zeek has to be able to call into your code with the C++ API 
that it expects, and your code has to be able to call back into Zeek.

The way that you outline - with the Rust code in its own library - 
sounds like the easiest alternative.

If Rust can directly call into C++ - and can generate a library that is 
callable in exactly the way that C++ expects, you might be able to make 
this work without the wrapper - but after a short peek into the 
documetation this does not seem trivially possible.
