如何在Rust中读取与自定义类型关联的枚举的值？

enum MyEnum {
    Variant1(u32),
    Variant2(String),
    Variant3(bool),
}

let my_enum = MyEnum::Variant1(42);

match my_enum {
    MyEnum::Variant1(value) => {
        println!("Variant1: {}", value);
    }
    MyEnum::Variant2(value) => {
        println!("Variant2: {}", value);
    }
    MyEnum::Variant3(value) => {
        println!("Variant3: {}", value);
    }
}
