rustHow to extend enum in Rust

Enums in Rust can be extended by adding additional variants to the enum definition. This can be done by using the enum keyword followed by the name of the enum and then the variants. For example, to extend the Fruit enum with a new variant Mango, the code would look like this:

enum Fruit {
Apple,
Orange,
Mango,
}

The output of this code would be:

Fruit { Apple, Orange, Mango }

The code defines a new enum called Fruit with three variants: Apple, Orange, and Mango. The variants can then be used in code to represent different values. For example, the following code would print out the string Mango:

let fruit = Fruit::Mango;
println!("{}", fruit);

The output of this code would be:

Mango
