I need to count 5 minutes from now in Rust. I thought I could use time::now() but it's deprecated. What can I use and how to do that?

推荐答案

如果您将鼠标悬停在文档中已弃用"的注释上，您会看到它指向rust-lang/time 存储库.基本上，它已经从标准库中移到了自己的包中.

If you mouse over the "deprecated" note in the documentation, you'll see that it points you to the rust-lang/time repository. Basically, it got moved out of the standard library into its own package.

如果您按照文档中的指定添加对 time 箱的依赖，则此方法有效:

Provided you add a dependency on the time crate as specified in the documentation, this works:

extern crate time;

use std::time::duration::Duration;

fn main() {
    let now = time::get_time();
    println!("now:   {}", now);
    let later = now + Duration::minutes(5);
    println!("later: {}", later);
}
