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 boxself::boxself;

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

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

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

fn main(){ let mut animals:Vec>=Vec::new(); animals.push(Box::new(Dog{})); animals.push(Box::new(Cat{})); for anim in animals{ anim.consume_boxed() } } ```

Motivation:

• [How to call a method that consumes self on a boxed trait object?]

Another solution on nightly Rust unsized_fn_params:

• [How to pass a boxed trait object by value in Rust?]
