nothing

nothing::[Probably] is a better [Option].

pub enum Probably {
    Nothing,
    Something(T),
}

Why?

The point is that you can use [Probably] as the return type of your main function:

use nothing::{Probably, Nothing};

fn main() -> Probably<()> {
    Nothing
}

Exit code is 0 if it is [Something], 1 if [Nothing].

You can even use the ? operator the way you would with [Option] and [Result]. See ./examples/main.rs

Probably nothing.
