有没有办法在Rust中“扁平化”(反)序列化的枚举？

[dependencies]
serde = "1.0"
serde_derive = "1.0"

use serde::{Serialize, Deserialize};

#[derive(Serialize, Deserialize)]
enum MyEnum {
    Variant1 {
        field1: u32,
        field2: String,
    },
    Variant2 {
        field3: bool,
    },
    // 其他变体...
}

use serde_json;

fn main() {
    let my_enum = MyEnum::Variant1 {
        field1: 42,
        field2: "Hello".to_string(),
    };

    // 序列化为JSON字符串
    let json_str = serde_json::to_string(&my_enum).unwrap();
    println!("Serialized: {}", json_str);

    // 反序列化为枚举类型
    let deserialized_enum: MyEnum = serde_json::from_str(&json_str).unwrap();
    println!("Deserialized: {:?}", deserialized_enum);
}
