Async Destruction

A smart pointer which executes drop asynchronously in tokio.

Basic usage

dependencies

```toml async_destruction = "0.1" tokio = { version = '1', features = ["full"] }

Only used in the current example

chrono = "0.4" ```

demo

```rust use async_destruction::AsyncDestruction; use chrono::Utc; use std::{thread::sleep, time::Duration};

[derive(Clone)]

struct S; impl Drop for S { fn drop(&mut self) { sleep(Duration::from_millis(1)); println!("drop!"); } }

[test]

fn itworks() { let a = vec![S; 10]; let t1 = Utc::now().timestampmillis(); drop(a); let t2 = Utc::now().timestamp_millis(); // will print 'drop cost time: 12ms' println!("drop cost time: {}ms", t2 - t1); }

[tokio::test]

async fn asyncworks() { let a = AsyncDestruction::new(vec![S; 10]); let t1 = Utc::now().timestampmillis(); drop(a); let t2 = Utc::now().timestamp_millis(); // will print 'drop cost time: 0ms' println!("drop cost time: {}ms", t2 - t1); } ```
