Контракт
- assert a pin_project struct containing an unannotated PhantomPinned field silently implements Unpin allowing safe in-place dereferencing via Pin::new and Pin::get_mut
- assert annotating a PhantomPinned field with #[pin] or applying #[project(!Unpin)] disables automatic Unpin implementation and requires unsafe Pin::new_unchecked construction
- assert a pin_project enum with unannotated PhantomPinned variant fields implements Unpin as long as its #[pin] variant fields implement Unpin
- assert project_replace moves out unpinned fields into ProjOwn while replacing the pinned struct and dropping pinned fields in-place
- assert projection types and project methods generated for pub structs have pub(crate) visibility rather than public export
