python - Rust:逐个字符打印出字符串

Question

它的任务是使用Rust将字符串的文本逐个字符地打印到终端上。

这是我的代码:

use std::time::Duration;
use std::thread::sleep;

fn main() {
    let string = "You are the Semicolon to my Statements.";

    for c in string.chars() {
        print!("{}", c);
        sleep(Duration::from_millis(100));
    }

    println!();
}

运行我的代码时，该字符串仅在循环完成后才打印到终端。

如何按字符打印字符串？

P.S.这是Python 3中的一个工作示例:

import time

string = "You are the Semicolon to my Statements."

for i in string:
    print(i, end='', flush=True)
    time.sleep(0.1)

print()

您需要找到如何在 rust 中使用flush，您的代码应如下所示

use std::time::Duration;
use std::thread::sleep;
use std::io::stdout;
use std::io::Write;

#[allow(unused_must_use)]
fn main() {

   let string = "You are the Semicolon to my Statements.";

   for c in string.chars() {
      print!("{}", c);
      stdout().flush();
      sleep(Duration::from_millis(10));
   };

   println!();

}
