108 `foo` now is of the type [`impl PinInit<Foo>`]. We can now use any smart pointer that we like
109 (or just the stack) to actually initialize a `Foo`:
112 let foo: Result<Pin<Box<Foo>>, AllocError> = Box::pin_init(foo);
170     pub struct foo {
174         pub fn init_foo(ptr: *mut foo);
175         pub fn destroy_foo(ptr: *mut foo);
177         pub fn enable_foo(ptr: *mut foo, flags: u32) -> i32;
183 /// `foo` is always initialized
189     foo: UnsafeCell<MaybeUninit<bindings::foo>>,
196         //   enabled `foo`,
201                 let foo = &raw mut (*slot).foo;
202                 let foo = UnsafeCell::raw_get(foo).cast::<bindings::foo>();
204                 // Initialize the `foo`
205                 bindings::init_foo(foo);
208                 let err = bindings::enable_foo(foo, flags);
210                     // Enabling has failed, first clean up the foo and then return the error.
211                     bindings::destroy_foo(foo);
225         // SAFETY: Since `foo` is initialized, destroying is safe.
226         unsafe { bindings::destroy_foo(self.foo.get().cast::<bindings::foo>()) };
