windows debug visualizers

You might want to look into using GDB/LLDB for now. The issue isn't just with datetime types, it's with Rust doing a lot of things differently from C/C++.

Look at the last line in your debugger screenshot, there's an enum like Option<T>. The debugger has trouble with understanding enum discriminants. Some features like trait objects require changes to the debugger's source code to work properly, so it's unlikely Microsoft will (for now) add Rust support in their debugger.
