exercism: implement reverse(input: &str) -> String me: input.chars().rev().collect() things really do compose nicely, it's good

I'm interested in whether there's a "more efficient" way of doing this except reversing strings is a thing I have literally never done in production

It depends on what you mean by “character”. If it was ascii, then very yes. Graphemes cluster? Well that code is already wrong. Friggin strings

I mean this is why you don't actually reverse a string I've never wanted to do that but if I did I'd reach for ICU

like, reversing "text" is extremely different from reversing "an array"

Just get an iterator over grapheme clusters and it's No Problem! https://crates.io/crates/unicode-segmentation …

Still nope. The problem is that reversing a string is not an operation that makes general sense anyway. It's pretty anglocentric to ask this question.
