extend-fn
Simple no-alloc library that allows using any arbitrary FnMut that takes a single value, in a place where types implementing Extend are needed.
use extend_fn::ExtendUsing;
let initial = [3, 8, 2usize];
let mut result = 0usize;
let mut extender = ExtendUsing::new(|value: usize| result += value);
extender.extend(initial.iter().copied());
assert_eq!(result, initial.into_iter().sum());
