It looks like there is an extern C interface... I wonder if it is everything necessary for someone to use it via FFI.

Given that it's being used in a large C++ codebase, I would assume it has everything needed to use it in that API.

They just need to rewrite the rest of Chrome to use the native Rust<>Rust interface.

(in reality Google is investing a lot of effort into automating the FFI layer to make it safer and less tedious)
