Example

use konst::ptr::nonnull;

use core::{
    ptr::NonNull,
    marker::PhantomData,
};

const A: NonNull<u8> = nonnull::from_ref(&3);
const A_REF: &u8 = unsafe{ nonnull::as_ref(A) };
assert_eq!(A_REF, &3);

const B: NonNull<str> = nonnull::from_ref("hello");
const B_REF: &str = unsafe{ nonnull::as_ref(B) };
assert_eq!(B_REF, "hello");
