The context of this exact discussion is the defense of the ugly Rust code above by Rust aficionados who see nothing wrong with it. That code came from the Embedded Rust working group in their learning material for Rust beginners. I'm not taking anything out of context. That code is hideous. It's terse. It uses controls and defenses that aren't needed for most embedded applications. It turned a beginner away from the language. When I provided much simpler C code as an alternative, Rust aficionados started to cry about unneeded mutexes, unneeded ref counting, the inability of programmers to remember to call free or mutex_unlock, etc. etc.
