Since a string supports iteration but not indexing, I would like to convert a string into a list of chars. I have "abc" and I want ['a', 'b', 'c'].
It can be any type as long as I can index into it. A Vec<char> or a [char; 3] would be fine, other ideas would also be interesting!
Faster would be better since I am dealing with very long strings. A version that is more efficient when assuming that the string is ASCII would also be cool.
Use the chars method on String or str:
fn main() {
let s = "Hello world!";
let char_vec: Vec<char> = s.chars().collect();
for c in char_vec {
println!("{}", c);
}
}
