panics are safe. You expect the “I don’t have a bug” case to be fast.
You can, but it depends on what you mean by “character”, as that’s not a concept in Unicode. Every kind of thing you could mean has a method, specific to it, since they’re different things.
(char in Rust is a Unicode scalar value, and you can collect into a Vec<char> and then slice it, as an example of one of those things. And that’s still O(1) at the cost of using up to four times the memory.)
