How to map enum values to integers (i32, u64) in Rust?

Hello colleagues! I've just started learning Rust and encountered a problem that seems simple, but I can't find an elegant solution. I have an enum `Color` that describes colors: ```rust enum Color { Red, Green, Blue, } ``` I want to assign an integer value to each variant, so that, for example, `Red` corresponds to 0, `Green` to 1, `Blue` to 2. And then I need: 1. Get a number from an enum variant (e.g., from `Color::Green` get `1`). 2. Do the reverse conversion: from a number (e.g., `2`) get the variant `Color::Blue`. In C++ or C# I would just write `(int)color` or `(Color)2`. In Python I would use a dictionary. But in Rust everything is stricter with types. I tried using `as`: ```rust let c = Color::Red; let n =
