lib.rs:

This library provides some utility traits to make working with [Any] smoother. This crate contains similiar functionality to the downcast crate, but simpler, e.g. it isn't necessary to call some macro to instantiate the downcast methods.

Usage example

use as_any::{AsAny, Downcast};

struct Test;

trait Custom: AsAny {
// whatever you like to put inside of your trait
}

impl Custom for Test {}

fn lol() {
let x = Test;
let y: &dyn Custom = &x;
// With (extension) trait `Downcast` in scope.
y.downcast_ref::<Test>().unwrap();
}
