# Trait std::marker::Unpin

    pub auto trait Unpin { }

Expand description

Types that can be safely moved after being pinned.

Rust itself has no notion of immovable types, and considers moves (e.g., through assignment or `mem::replace`) to always be safe.

The `Pin` type is used instead to prevent moves through the type system. Pointers `P<T>` wrapped in the `Pin<P<T>>` wrapper can’t be moved out of. See the `pin` module documentation for more information on pinning.

Implementing the `Unpin` trait for `T` lifts the restrictions of pinning off the type, which then allows moving `T` out of `Pin<P<T>>` with functions such as `mem::replace`.

`Unpin` has no consequence at all for non-pinned data. In particular, `mem::replace` happily moves `!Unpin` data (it works for any `&mut T`, not just when `T: Unpin`). However, you cannot use `mem::replace` on data wrapped inside a `Pin<P<T>>` because you cannot get the `&mut T` you need for that, and that is what makes this system work.

So this, for example, can only be done on types implementing `Unpin`:

    use std::mem;
    use std::pin::Pin;

    let mut string = "this".to_string();
    let mut pinned_string = Pin::new(&mut string);

    // We need a mutable reference to call `mem::replace`.
    // We can obtain such a reference by (implicitly) invoking `Pin::deref_mut`,
    // but that is only possible because `String` implements `Unpin`.
    mem::replace(&mut *pinned_string, "other".to_string());

Run

This trait is automatically implemented for almost every type.
