§autotrait

Sometimes you want to do dynamic dispatch. First you’d have to define a trait:

trait Trait {
    fn do_stuff(&self) -> String;
}

And then implement it on something:

struct Impl;

impl Trait for Impl {
    fn do_stuff(&self) -> String {
        // do stuff here
        todo!()
    }
}

We’re repeating ourselves a bunch when doing that! What if we could just do:

struct Impl;

#[autotrait::autotrait]
impl Trait for Impl {
    fn do_stuff(&self) -> String {
        // do stuff here
        todo!()
    }
}

That way we wouldn’t even have to define the trait!

Well, that’s what this crates does.
