I recently rewrote a complex C++ program into Rust using the Strangler Mode, all codes are written by AI. Firstly, I split the code into some dynamic libraries, which uses C ABI to interacts with each other. Secondly, rewrite the libraries one by one. A init_xxx function are used to construct a object and a free_xxx is used to deconstruct it. A handle is used as 'this' pointer. In the caller side, write another class, constructor calls init_xxx and deconstructor calls free_xxx. No other code should be modified during the split.
