When writing a no_std binary, you'll be greeted with nonsensical errors mentioning lang items like eh_personality and start. That's pretty bad because it makes you think that you need to define them somewhere! But oh no, now you're getting the `internal_features` lint telling you that you shouldn't use them! But you need a no_std binary! What now? No problem! Writing a no_std binary is super easy. Just use panic=abort and supply your own platform specific entrypoint symbol (like `main`) and you're good to go. Would be nice if the compiler told you that, right? This makes it so that it does do that.
