How to print enum in Rust

// plain

In Rust, you can print an enum by using the println! macro. To do this, you must first define the enum and then use the {:?} formatting specifier to print it. For example, if you have an enum called MyEnum with two variants, Variant1 and Variant2, you can print it like this:

enum MyEnum {
    Variant1,
    Variant2,
}

let my_enum = MyEnum::Variant1;
println!("{:?}", my_enum);

This will print Variant1 to the console. The {:?} formatting specifier is a shorthand for the Debug trait, which is used to print out the value of an enum.
