Rust 为什么实现特征的对象期望比具体对象有更长的生命周期

几年来，我一直把Rust 作为一种爱好.就在我以为我开始理解生命的时候，我发现了这个.我试图"泛化"一个函数来处理不同类型的数据.以下是我的问题的MRE.

pub struct BorrowedData<'data> {
    inner: Vec<&'data u16>
}

struct ConcreteData {
    data: Vec<u16>
}

impl TryFrom<BorrowedData<'_>> for ConcreteData {
    type Error = ();

    fn try_from(value: BorrowedData<'_>) -> Result<Self, Self::Error> {
        Ok(Self {
            data: value.inner.into_iter().map(|n| *n).collect()
        })
    }
}


pub fn test_generic<'data,Entity: TryFrom<BorrowedData<'data>,Error=()>>() -> Result<(),()> {

    let data = [4,8,15,16,23,42];

    let borrowed = BorrowedData {
        inner: data.iter().collect()
    };

    let _data = Entity::try_from(borrowed)?;

    // ...Process and save data to file in appropriate structure

    Ok(())

} // data dropped here while still borrowed?

pub fn test_concrete() -> Result<(),()> {

    let data = [4,8,15,16,23,42];

    let borrowed = BorrowedData {
        inner: data.iter().collect()
    };

    let _data = ConcreteData::try_from(borrowed)?;

    // ...Process and save data to file in appropriate structure

    Ok(())

}

这将返回编译错误:

error[E0597]: `data` does not live long enough
  --> src/mre.rs:26:16
   |
21 | pub fn test_generic<'data,Entity: TryFrom<BorrowedData<'data>,Error=()>>() -> Result<(),()> {
   |                     ----- lifetime `'data` defined here
...
26 |         inner: data.iter().collect()
   |                ^^^^^^^^^^^ borrowed value does not live long enough
...
29 |     let _data = Entity::try_from(borrowed)?;
   |                 -------------------------- argument requires that `data` is borrowed for `'data`
...
35 | } // data dropped here while still borrowed?
   | - `data` dropped here while still borrowed

它在具体函数中工作得很好，但泛型函数会带来问题.

有谁能解释一下这个吗？

有没有办法修复test_generic的功能？*或者这是不可能的？

*不接触data变量或BorrowedData struct .后者是对从外部c库调用返回的对象的模拟，前者是因为它是我重现错误的唯一方法.这是我在我的真实代码中得到的错误.
