Lifetime Thread

A lock-free thread with a lifetime. Divide a value into master and slave. After the lifetime of the master value ends, the slave value will not be accessible.


Introduction

A lock-free thread with a lifetime. Divide a value into master and slave. After the lifetime of the master value ends, the slave value will not be accessible.

scenes to be used:

  • An operation needs to be performed in the background, but the lifetime is not static
  • ...

Basic usage

use std::{thread, time::Duration};

#[test]
fn it_works() {
    let s = "xxx";
    let outer = lifetime_thread::spawn(s, |inner| {
        println!("begin");
        while let Some(t) = inner.get() {
            println!("ok! {}", t);
            assert_eq!(*t, "xxx");
            thread::sleep(Duration::from_millis(1));
        }
        println!("over")
    });
    thread::sleep(Duration::from_millis(10));
    assert_eq!(*outer, "xxx")
}

#[tokio::test]
async fn async_works() {
    let s = "xxx";
    let outer = lifetime_thread::async_spawn(s, |inner| async move {
        println!("begin");
        while let Some(t) = inner.get() {
            println!("ok! {}", t);
            assert_eq!(*t, "xxx");
            tokio::time::sleep(Duration::from_millis(1)).await;
        }
        println!("over")
    });
    tokio::time::sleep(Duration::from_millis(10)).await;
    assert_eq!(*outer, "xxx");
    drop(outer);
}

output:

begin
ok! xxx
ok! xxx
...
...
ok! xxx
over
