Hey I made a library to simplify the process of making plugins for your applications in rust. Basically what it does is it makes possible to pass complex types between host and guest environments and simplifies calling guest functions. https://github.com/ItsEthra/scotch

There's the abi_stable crate, which provides safe ffi between shared libraries and applications, I also made a simple example (only using the libloading crate), it's as fast as it can be, since there's no extra overhead, but it's not ffi safe and a small change in any of the vtables (traits) can cause segfaults (you can add a version check though)
