# Drop detection library for Rust

With Clone, Sync, Send and optional PartialEq + Hash support.

## Examples

```rust

use std::sync::{Arc, Mutex};

use dropcatch::DropCatcher;

// flag to track the dropped state

let flag = Arc::new(Mutex::new(false));

let flag_clone = flag.clone();

{

    let dropped = DropCatcher::new(move || {

        // called when DropCatcher is dropped

        *flag_clone.lock().unwrap() = true;

    });

    let dropped_clone = dropped.clone();

    assert_eq!(dropped, dropped_clone); // same instance

    drop(dropped);

    assert!(!*flag.lock().unwrap()); // not still dropped

}

assert!(*flag.lock().unwrap()); // dropped

```
