Rust split string by nothing

In js I would do this

"abc".split("") // ["a","b","c"]

I want something simlimar in rust

let splits = String::from("abc").split("") // does not work with empty string!!! 
let letters = (
  splits.next().unwrap(),
  splits.next().unwrap(),
  splits.next().unwrap(),
) // ('a','b','c') 

I want something simlimar in rust but it does not work. no error no nothing

>Solution :

You could use this:

let s = String::from("abc");
let mut chars = s.chars();

let letters = (
    chars.next().unwrap(),
    chars.next().unwrap(),
    chars.next().unwrap(),
);
