rustrust string chars

A String in Rust is a UTF-8 encoded sequence of bytes. It is a collection of characters, and each character is represented by a char type.

let s = String::from("Hello, world!");

for c in s.chars() {
    println!("{}", c);
}

The output of the above code is:

H
e
l
l
o
,

w
o
r
l
d
!

The chars() method of a String returns an iterator over the characters of the string. This iterator can be used to iterate over the characters of the string.

The char type in Rust is a Unicode scalar value, which means it can represent a code point in any Unicode code point range.
