# box-self

Easy way to duplicate a new function with `self: Box<Self>` signature.

Sometimes you need both functions `fn consume(self)` and `fn consume_boxed(self: Box<Self>)`. This macro generates the second one for you.

## Examples
```rust
   use box_self::box_self;

   trait Animal {
       fn consume(self);
       fn consume_boxed(self: Box<Self>);
   }

   struct Dog{}
   impl Animal for Dog{
       #[box_self(_boxed)]
       fn consume(self) {
           println!("Bark");
       }
   }

   struct Cat{}
   impl Animal for Cat{
       #[box_self(_boxed)]
       fn consume(self) {
           println!("Jump");
       }
   }

   fn main(){
       let animals:Vec<Box<dyn Animal>>=
            vec![Box::new(Dog{}), Box::new(Cat{})];

       for anim in animals{
           anim.consume_boxed();
       }
   }
```
