dispatch-lite

Lightweight enum dispatch for trait objects — a minimal alternative to enum_dispatch with a smaller dependency footprint.

Usage

Apply #[dispatch_lite] to a trait definition:

use dispatch_lite::dispatch_lite;

#[dispatch_lite]
trait Animal {
    fn sound(&self) -> String;
}

struct Dog;
struct Cat;

impl Animal for Dog { fn sound(&self) -> String { "woof".into() } }
impl Animal for Cat { fn sound(&self) -> String { "meow".into() } }

enum Pet { Dog(Dog), Cat(Cat) }
