pub(crate) struct SendPtr<T>(pub(crate) *mut T);Expand description
We need to transmit raw pointers across threads. It is possible to do this
without any unsafe code by converting pointers to usize or to AtomicPtr
Unsafe code is still required to dereference the pointer, so this type is not unsound on its own, although it does partly lift the unconditional !Send and !Sync on raw pointers. As always, dereference with care.
