Struct MultitraitObject

pub struct MultitraitObject { /* private fields */ }

A container to store data with the associated type and trait objects allowing for casting down to trait_impl or the concrete type

use multi_trait_object::*;
use std::fmt::{Debug, Display};

let mto = create_object!(String::new(), dyn Debug, dyn Display);

let debug = mto.downcast_trait::<dyn Debug>().unwrap();
println!("{:?}", debug);
let display = mto.downcast_trait::<dyn Display>().unwrap();
println!("{}", display);
let string = mto.downcast::<String>().unwrap();
println!("{}", string);
