Function compose 

pub fn compose<A, B, C, F, G>(f: F, g: G) -> impl Fn(A) -> C
where
    F: Fn(B) -> C,
    G: Fn(A) -> B,

Backward composition of two functions.

Arguments

• f - A function that takes a value in B and returns a value in C
• g - A function that takes a value in A and returns a value in B

Returns

A new function that takes a value in A and returns a value in C

Example

use overture_core::compose::compose;

let add_one = |x: i32| x + 1;
let multiply_by_two = |x: i32| x * 2;
let composed = compose(multiply_by_two, add_one);

assert_eq!(composed(5), 12); // (5 + 1) * 2 = 12
