How can I generate random string in Rust?

If you want a sequence of printable ASCII characters, you can use gen_ascii_chars function.

If you want a sequence of random bytes (like the C++ code you've written), you can use gen_iter:: function.

If you want a sequence of random Unicode code points (strictly speaking, Unicode Scalar Values), then gen_iter:: function.

Example of generating random string in Rust

#![allow(unstable)]

use std::rand::{self, Rng};

fn main() {
    let s = rand::thread_rng()
        .gen_ascii_chars()
        .take(10)
        .collect::<String>();
        
    println!("random string: {}", s);
}
