rgb_match

Instructions

Implement the struct Color with the function swap. This function must allow you to swap the values of the struct.

Notions

Expected functions

impl Color {
    pub fn swap(mut self, first: u8, second: u8) -> Color {}
    }

Usage

Here is a program to test your function.

use rgb_match::rgb_match;

struct Color {
    r: u8,
    g: u8,
    b: u8,
    a: u8,
}

fn main() {
    let c = Color {
        r: 255,
        g: 200,
        b: 10,
        a: 30,
    };

    println!("{:?}", c.swap(c.r, c.b));
    println!("{:?}", c.swap(c.r, c.g));
    println!("{:?}", c.swap(c.r, c.a));
    println!();
    println!("{:?}", c.swap(c.g, c.r));
    println!("{:?}", c.swap(c.g, c.b));
    println!("{:?}", c.swap(c.g, c.a));
    println!();
    println!("{:?}", c.swap(c.b, c.r));
    println!("{:?}", c.swap(c.b, c.g));
    println!("{:?}", c.swap(c.b, c.a));
    println!();
    println!("{:?}", c.swap(c.a, c.r));
    println!("{:?}", c.swap(c.a, c.b));
    println!("{:?}", c.swap(c.a, c.g));
}

And its output
