当我试图反序列化元组中的值时，它不允许我将结果推入数组。

fn main() {
    let raw_value = vec![(1, ("a", "a", 1))];

    //serialise
    let mut serialized_value = vec![];

    for val in raw_value.iter() {
        serialized_value.push((
            bincode::serialize(&val.0).unwrap(),
            bincode::serialize(&val.1).unwrap(),
        ));
    }

    //deserialise
    let mut deserialized_value: Vec<(&str, &str, i32)> = vec![];

    for val in serialized_value {
        deserialized_value.push(bincode::deserialize(&val.1).unwrap());
    }
}

它将发出以下错误：

error[E0597]: `val.1` does not live long enough
  --> src/main.rs:18:54
   |
18 |         deserialized_value.push(bincode::deserialize(&val.1).unwrap());
   |         ---------------------------------------------^^^^^^-----------
   |         |                                            |
   |         |                                            borrowed value does not live long enough
   |         borrow later used here
19 |     }
   |     - `val.1` dropped here while still borrowed

但是如果我重构值使其不在元组中，那么这样做就可以了。
知道为什么吗？
