Macro unique_type::new

macro_rules! new {
    () => { ... };
}

Generates a unique type that implements the Unique trait

Example

Calling this macro twice will always generate two different types, thus this will panic:

assert_eq!(
    TypeId::of::<unique_type::new!()>(),
    TypeId::of::<unique_type::new!()>()
);

And this won’t even compile:

let a: unique_type::new!() = todo!();
let b: unique_type::new!() = a;
