Crate dispatch_lite 

dispatch-lite

Lightweight enum dispatch for trait objects.

A minimal alternative to dynamic dispatch — apply #[dispatch_lite] to a trait and enum pair to generate zero-cost static dispatch.

Usage

use dispatch_lite::dispatch_lite;

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

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

Attribute Macros
