Coproduct
Have you ever found yourself in a situation where you'd like to have two enums where only a few variants differ? Usually that involves a lot of duplication and boilerplate. Not any more! Coproducts allow you to describe them and convert between them effortlessly!
use coproduct::{Coproduct, MkUnion, Union};
#[derive(Debug)]
struct A;
#[derive(Debug)]
struct B;
#[derive(Debug)]
struct C;
#[derive(Debug)]
struct D;
type ABC = MkUnion!(A, B, C);
fn main() {
let abc: Coproduct<ABC> = Coproduct::inject(A);
let abcd: Coproduct<Union<D, ABC>> = abc.embed();
println!("{:?}", abcd);
}
