+/// This trait allows creating an instance of `Self` which contains exactly one
+/// [structurally pinned value](https://doc.rust-lang.org/std/pin/index.html#projections-and-structural-pinning).
+///
+/// This is useful when using wrapper `struct`s like [`UnsafeCell`] or with new-type `struct`s.
+///
+/// # Examples
+///
+/// ```
+/// # use core::cell::UnsafeCell;
+/// # use pin_init::{pin_data, pin_init, Wrapper};
+///
+/// #[pin_data]
+/// struct Foo {}
+///
+/// #[pin_data]
+/// struct Bar {
+///     #[pin]
+///     content: UnsafeCell<Foo>
+/// };
+///
+/// let foo_initializer = pin_init!(Foo{});
+/// let initializer = pin_init!(Bar {
+///     content <- UnsafeCell::pin_init(foo_initializer)
+/// });
+/// ```
