rustWhat is an enum variable in Rust?

An enum variable in Rust is a type of data structure that allows a programmer to define a set of named constants. It is a type-safe way to represent a set of related values. Enums can be used to create a set of related constants, such as a set of colors or a set of days of the week.

Example code

enum Color {
    Red,
    Green,
    Blue,
}

fn main() {
    let color = Color::Red;
    println!("The color is {}", color);
}

Output example

The color is Red

Code explanation

1. enum Color { - This line declares an enum type called Color.
2. Red, - This line declares a constant called Red.
3. let color = Color::Red; - This line assigns the constant Red to the variable color.
4. println!("The color is {}", color); - This line prints the value of the variable color.
