Types that can be mapped over by receiving or returning references to their contents.

Examples

use fp_library::{brands::*, functions::*, types::*};

let memo = Lazy::<_, RcLazyConfig>::new(|| 10);
let mapped = ref_map::<LazyBrand<RcLazyConfig>, _, _, _>(
    |x: &i32| *x * 2,
    memo
);
assert_eq!(*mapped.evaluate(), 20);
