How to serialize enum in Rust

// plain

To serialize an enum in Rust, you can use the #[derive(Serialize)] attribute on the enum definition. This will allow you to serialize the enum into a JSON or other format. For example, if you have an enum like this:

#[derive(Serialize)]
enum Color {
    Red,
    Blue,
    Green,
}

You can serialize it into a JSON string like this:

let color = Color::Red;
let serialized = serde_json::to_string(&color).unwrap();

The output of this code will be "Red".

Detailed ## Explanation The #[derive(Serialize)] attribute is used to tell the Rust compiler that the enum should be serialized. This attribute is part of the serde crate, which is used to serialize and deserialize data. The serde_json::to_string function is used to serialize the enum into a JSON string. The unwrap function is used to convert the Result type returned by the to_string function into the actual string.
