rustHow to display enum in Rust

Enums in Rust can be displayed using the println! macro. To do this, the enum must first be declared with the enum keyword. For example, the following code creates an enum called Color with three variants: Red, Green, and Blue:

enum Color {
    Red,
    Green,
    Blue,
}

The enum can then be printed using the println! macro, as shown below:

println!("{:?}", Color::Red);

This will output the following:

Red

The println! macro uses the Display trait to print the enum, which is why the {:?} is used. This allows the enum to be printed in a readable format.
