    let mut name = String::from("JiangBo");
    println!("{:?}", unsafe { name.get_unchecked_mut(5..) });
}

split_at

    let name = "JiangBo";
    println!("{:?}", name.split_at(5));
}

split_at_mut

fn main() {
    let mut name = String::from("JiangBo");
    println!("{:?}", name.split_at_mut(5));
}

chars

    let name = "JiangBo";
    name.chars().for_each(|c| println!("{c}"));
}

char_indices

fn main() {
    let name = "JiangBo";
    name.char_indices().for_each(|e| println!("{e:?}"));
}

bytes

fn main() {
    let name = "JiangBo";
    name.bytes().for_each(|e| println!("{e:?}"));
}

split_whitespace

fn main() {
    let name = "Jiang Bo";
    name.split_whitespace().for_each(|e| println!("{e:?}"));
}

split_ascii_whitespace

fn main() {
    let name = "Jiang Bo";
    name.split_ascii_whitespace()
        .for_each(|e| println!("{e:?}"));
}
