async-std in Windows cdylib dlls (LoadLibrary/FreeLibrary startup/cleanup) about async-std

You can add two exported functions to your DLL, and move initial/uninitial code from DllMain to new func, such as:

// cpp pseudo code
typedef void(*pFinishCb)();
__declspec(dllexport) void AsyncInitialize(pFinishCb cb) {
    std::thread([](){
        // do something...
        cb();
    }).detach();
}
__declspec(dllexport) void AsyncUninitialize(pFinishCb cb) {
    std::thread([](){
        // do something...
        cb();
    }).detach();
}

and wrap it to async rust func:

// rust pseudo code
async fn MyAsyncInitialize() {
    cpp::LoadLibrary();
    let (tx, rx) = mpsc::channel();
    cpp::AsyncInitialize(move ||{
        tx.send(());
    });
    rx.recv().await;
}
// and same to Unitialize

now you can async initialize/uninitialize your dll in async:

MyAsyncInitialize().await;
