Let's see how pinning and the `Pin` type can help us solve this problem.
The `Pin` type wraps pointer types, guaranteeing that the values behind the
pointer won't be moved. For example, `Pin<&mut T>`, `Pin<&T>`,
`Pin<Box<T>>` all guarantee that `T` won't be moved if `T: !Unpin`.
pointer won't be moved if it is not implementing `Unpin`. For example, `Pin<&mut
T>`, `Pin<&T>`, `Pin<Box<T>>` all guarantee that `T` won't be moved if `T:
!Unpin`.
Most types don't have a problem being moved. These types implement a trait
called `Unpin`. Pointers to `Unpin` types can be freely placed into or taken
