C-like - Rust By Example
Description: A description

# C-like

`enum` can also be used as C-like enums.

    // An attribute to hide warnings for unused code.
    #![allow(dead_code)]

    // enum with implicit discriminator (starts at 0)
    enum Number {
        Zero,
        One,
        Two,
    }

    // enum with explicit discriminator
    enum Color {
        Red = 0xff0000,
        Green = 0x00ff00,
        Blue = 0x0000ff,
    }

    fn main() {
        // `enums` can be cast as integers.
        println!("zero is {}", Number::Zero as i32);
        println!("one is {}", Number::One as i32);

        println!("roses are #{:06x}", Color::Red as i32);
        println!("violets are #{:06x}", Color::Blue as i32);
    }
