Struct closure_cacher::RefCacher[−][src]

pub struct RefCacher<'a, I, O, T> { /* fields omitted */ }

RefCacher Struct that allows provision of a closure and memoizes its output using references for its input values

Examples

use closure_cacher::RefCacher;
let mut ref_cacher = RefCacher::new(|x| x + 1);
assert_eq!(ref_cacher.get(&1), &2);
