pub trait Drop {
    fn drop(&mut self);
}

The Drop`Drop` trait is used to run some code when a value goes out of scope. This is sometimes called a 'destructor'.

Examples

A trivial implementation of Drop`Drop. The`. The drop`dropmethod is called when` method is called when _x`_xgoes out of scope, and therefore` goes out of scope, and therefore main`mainprints` prints Dropping!`Dropping!`.

struct HasDrop; impl Drop for HasDrop { fn drop(&mut self) { println!("Dropping!"); } } fn main() { let _x = HasDrop; }
struct HasDrop;

impl Drop for HasDrop {
    fn drop(&mut self) {
        println!("Dropping!");
    }
}

fn main() {
    let _x = HasDrop;
}

Required Methods
