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
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();
}
