Thex<T> allows data races of non-Send types across threads

thex::Thex implements Sync for all types T. However, it is missing a bound for T: Send. This allows non-Send types such as Rc to be sent across thread boundaries which can trigger undefined behavior and memory corruption...

RUSTSEC-2020-0151 Generators can cause data races if non-Send types are used in their generator functions

The Generator type is an iterable which uses a generator function that yields values. In affected versions of the crate, the provided function yielding values had no Send bounds despite the Generator itself implementing Send. The generator function lacking a Send bound means that types that are...

Queue<T> should have a Send bound on its Send/Sync traits

Affected versions of this crate unconditionally implements Send/Sync for Queue. This allows 1 creating data races to a T: !Sync and 2 sending T: !Send to other threads, resulting in memory corruption or other undefined behavior...
