use everything_sdk::raw::*;

// It looks no different from the ergonomic wrapper, why can't we just write the code like this?
//
// Think about that:
//   For any `Everything_*` function as below, we insert another `Everything_*` function between
//   them, which will cause the modifications of the mutable global shared states (the underhood
//   we know they are just the global static variables in C code), because they all have access
//   to them. Finally it will cause _everything_ to become messy, uncontrollable and unreliable.
//
// All we can do is to line them up, in some certain order, and let them move forward one by one
// to prevent chaos.
