When I've dabbled in C++ in the past, worrying about safety (does my custom trie implementation segfault? is this iterator still valid? can I trust the code I just vendored into my repo?) was the main source of complexity, both in initial writing of my code and in debugging it. Working in Rust has been a comparative (and simple) delight for me.
