Crate async_drop 

Async drop support for Rust.

This crate provides AsyncDrop, a trait for types that need to perform asynchronous cleanup, and Dropper, a wrapper that automatically runs the async cleanup when the value is dropped.

Example

use async_drop::{AsyncDrop, AsyncDropFuture, Dropper};

struct DbConnection;

impl AsyncDrop for DbConnection {
    fn async_drop(&mut self) -> AsyncDropFuture<'_> {
        Box::pin(async {
            // Close the connection gracefully...
            Ok(())
        })
    }
}

let conn = Dropper::new(DbConnection);
// Use `conn` as if it were a `DbConnection` (via Deref).
// When `conn` goes out of scope, `async_drop` runs automatically.
