Summary
Multiple soundness issues in `Ptr`
Details
Affected versions of this crate have the following issues:
-
PtrimplementsSendandSyncfor all types, this can lead to data races by sending non-thread safe types across threads. -
Ptr::getviolates mutable alias rules by returning multiple mutable references to the same object. -
Ptr::writeuses non-atomic writes to the underlying pointer. This means that when used across threads it can lead to data races.
