  Defines route lifecycle method [onDeactivate], which is called by the router before destroying
  a component as part of a route change.
  
  If `onDeactivate` returns a promise, the route change will wait until the promise settles.
  
  ## Example
  ```
  @Directive({
    selector: 'my-cmp'
  })
  class MyCmp implements CanReuse, OnReuse {
    canReuse() {
      return true;
    }
  
    onReuse(next, prev) {
      this.params = next.params;
    }
  }
   ```
