Summary

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

Details

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 dangerous to send across threads such as Rc could be sent as part of a generator, potentially leading to data races.

This flaw was fixed in commit <code>f7d120a3b</code> by enforcing that the generator function be bound by Send.
