Description
Affected versions of this crate have the following issues:
-
Ptr
implements Send
and Sync
for all types, this can lead to data
races by sending non-thread safe types across threads.
-
Ptr::get
violates mutable alias rules by returning multiple mutable
references to the same object.
-
Ptr::write
uses non-atomic writes to the underlying pointer. This means
that when used across threads it can lead to data races.
