Functionality

Adds support for chaining functions in a functional way.

Pipe

The following 9 methods are added to all types:

These are imported directly from the pipe-trait crate.

Example

use functionality::prelude::*;

let inc = |x| x + 1;
let double = |x| x + x;
let square = |x| x * x;
let a = (123i32).pipe(inc).pipe(double).pipe(square);
let b = square(double(inc(123i32)));
assert_eq!(a, b);

Mutate

The method .mutate(..) is also added to all types.

Example

use functionality::prelude::*;

let sorted = vec![3, 2, 1].mutate(|v| v.sort());
assert_eq!(sorted, vec![1, 2, 3]);

Future Plans

I plan on coming back to this crate and adding more useful things to it. If you have any ideas, please send them to me! Contact me at yony252525@gmail.com.

I do want to only put important, useful things in this crate. For example, I thought about adding a macro to make piping easier (something like pipe! { input |> f1 |> f2 |> ... }) but it sounded not nearly as essential as .pipe and .mutate for my kind of programing.
