Macro for dropping the fields of a struct or enum without dropping the container.

## Usage

Add `#[derive(DestructDrop)]` to your `struct` or `enum` definition.

```rust

use destruct_drop::DestructDrop;

#[derive(DestructDrop)]

struct Container {

    inner: Inner

}

struct Inner;

impl Drop for Container {

    fn drop(&mut self) {

        println!("dropped Container");

    }

}

impl Drop for Inner {

    fn drop(&mut self) {

        println!("dropped Inner");

    }

}

fn main() {

    // prints "dropped Inner" and then "dropped Container"

    drop(Container { inner: Inner });

    // prints only "dropped Inner"

    Container { inner: Inner }.destruct_drop();

}

```
