Module ref_functor 

A type class for types that can be mapped over, returning references.

Examples

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

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