以带有serde的字符串形式获取枚举变量的名称

use serde::{Serialize, Deserialize};

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

fn main() {
    let color = Color::Red;
    let serialized_color = serde_json::to_string(&color).unwrap();
    println!("Serialized color: {}", serialized_color);

    // 如果你想要直接获取枚举变量的名称作为字符串，你可以这样做：
    let color_name = match color {
        Color::Red => "Red",
        Color::Green => "Green",
        Color::Blue => "Blue",
    };
    println!("Color name: {}", color_name);
}

use serde::{Serializer, Deserialize};

impl Serialize for Color {
    fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>
    where
        S: Serializer,
    {
        let name = match self {
            Color::Red => "Red",
            Color::Green => "Green",
            Color::Blue => "Blue",
        };
        serializer.serialize_str(name)
    }
}
