done :D

use std::io;

fn main() {
    let mut input: String = String::new();
    let stdin = io::stdin();

    let x = rand::random::<u32>() % 101;
    let mut attempts = 0;

    let mut user_inputs: Vec<u32> = Vec::new();
    loop {
        println!("Guess a number from 0 to 100:");
        stdin.read_line(&mut input);
        input = input.to_string().replace("\n", ""); // removing the \n
        let user_input: u32 = input.parse::<u32>().unwrap();
	user_inputs.push(user_input);
        if x == user_input {
            println!("You won! attempts: {attempts}");
	    println!("Your inputs:");
	    for input in user_inputs {
		print!("{input} ");
	    }
	    println!("");
            break;
        }
        else if x < user_input {
            println!("too big");
            attempts += 1;
        }
        else {
            println!("too small");
            attempts += 1;
        }
        input.clear()
    }
}

but to do that I have to use external deps? which I am not comfortable doing. (I am newbie :) )
