You can actually use the IDF system in Rust to use the std lib, at least on ESP32-C3. Probably others too.

If you are on Windows, you will need to place the project folder at the top level drive directory, and there are other quirks as well, but it works.

Haha yes, I misphrased a bit but that's what I meant when I said you'll need to use C++ to use the stdlib. It's not quite pure embedded Rust but yes it does work.
