In my little experience with rust, things can get ugly very quickly, but it depends very much on the task. I wrote a game server monitor, and a fairly extensive command line calculator in rust, and that code for all those looks quite fancy. I wrote a tool that converts a lexicon to a trie and one that can do error correction using that trie, and that has some quirks. I also tried porting an Earley parser from C, and that took a nasty turn, since it relies a lot on pointer sharing.

I have more experience writing in Go, and I think the code for all would look similar-ish. Go is a bit of a grey language, but it gets the job done without a lot of refactoring and restructuring.
