pub fn recur_fn<Arg, Output, F>(body: F) -> Closure<F> where
    F: Fn(&dyn Fn(Arg) -> Output, Arg) -> Output, 

Constructs a RecurFn with the body speicified.

Examples

use recur_fn::{recur_fn, RecurFn};

let fib = recur_fn(|fib, n: i32| {
    if n <= 1 {
        n
    } else {
        fib(n - 1) + fib(n - 2)
    }
});

assert_eq!(55, fib.call(10));
