Struct SendPtr

Source

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 then back to a raw pointer for use. We prefer this approach because code that uses this type is more explicit.

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.
