Thanks for the link! I have gone through that page and the instructions are thorough. There are projects like CXX (https://cxx.rs/) that help with the Rust <--> C++ stuff, but to be honest, I am new to Rust (Python is one I'm more familiar with, but I am not interested in writing the hook in Python at this stage - speed https://stackoverflow.com/questions/801657/is-python-faster-and-lighter-than-c and type safety). I assume something is wrong with how I'm linking against Kea, but I don't know. Unfortunately, the debug log during hook loading is not terribly helpful. I am confident it's possible, though.

At least from what little i've done, it didn't seem so... it seemed they had their own API and an application to search user created extensions for such. The developer's guide I linked says it should be possible to create hooks in other languages. They mention Python. I'd say Rust is way closer to C++ the Python is... so it should be possible?
