Ambos errores ocurren porque el tipo `Pin<Box<SelfReferential>>` ya no implementa el trait `DerefMut`. Esto es exactamente lo que queremos porque el trait `DerefMut` devolvería una referencia `&mut`, que queremos prevenir. Esto solo ocurre porque ambos optamos por no implementar `Unpin` y cambiamos `Box::new` a `Box::pin`.

どちらのエラーも、`Pin<Box<SelfReferential>>` 型が `DerefMut` trait を実装しなくなったために発生します。これはまさに求めていた結果であり、というのも、`DerefMut` trait は `&mut` 参照を返してしまうからで、私達はこれを防ぎたかったのです。これは、`Unpin` を使用しないようにして、`Box::new` を `Box::pin` に変更したからこそ起こる現象です。 どちらのエラーも、`Pin<Box<SelfReferential>>` 型が `DerefMut` trait を実装しなくなったために発生します。これはまさに求めていた結果であり、というのも、`DerefMut` trait は `&mut` 参照を返してしまうからで、私達はこれを防ぎたかったのです。これは、`Unpin` を使用しないようにして、`Box::new` を `Box::pin` に変更したからこそ起こる現象です。

Both errors occur because the `Pin<Box<SelfReferential>>` type no longer implements the `DerefMut` trait. This is exactly what we wanted because the `DerefMut` trait would return a `&mut` reference, which we wanted to prevent. This only happens because we both opted-out of `Unpin` and changed `Box::new` to `Box::pin`. Both errors occur because the `Pin<Box<SelfReferential>>` type no longer implements the `DerefMut` trait.

这两个错误的发生是因为 `Pin<Box<SelfReferential>>` 类型不再实现 `DerefMut` trait。这正是我们想要的，因为 `DerefMut` trait 会返回一个 `&mut` 引用，而这正是我们想要避免的。这种情况之所以发生，仅仅是因为我们同时选择了不实现 `Unpin` 并将 `Box::new` 改为 `Box::pin`。 这两个错误的发生是因为 `Pin<Box<SelfReferential>>` 类型不再实现 `DerefMut` trait。这正是我们想要的，因为 `DerefMut` trait 会返回一个 `&mut` 引用，而这正是我们想要避免的。这种情况之所以发生，仅仅是因为我们同时选择了不实现 `Unpin` 并将 `Box::new` 改为 `Box::pin`。

由於 `Pin<Box<SelfReferential>>` 類型不再實現 `DerefMut` 特型，所以這兩個錯誤都發生了。 由於 `Pin<Box<SelfReferential>>` 類型不再實現 `DerefMut` 特型，所以這兩個錯誤都發生了。
