Research direction

Start by reading the existing AtomicRef API and the linked discussion about the partial implementation. Clarify the ownership, borrowing, blocking, and into_inner semantics for an AtomicWeakRef; done means those behaviors are specified and covered by appropriate tests.

Written by the indexing model from the issue text.

Description

Would it be possible to add a weak reference type to this library that doesn't include a lifetime parameter?
I've been trying to create something similar to "Box" but with thread-safe weak pointers;
or "Arc" but with the ability to into_inner and get the original value out.

Your library almost satisfies my requirements, but the lifetime requirement on the AtomicRef was problematic.

For reference:
https://www.reddit.com/r/rust/comments/1aq8zzf/help_implementing_an_atomic_reference_box_type/

Note that in my partial-implementation, the into_inner function can block until the weak references aren't actively borrowing. Not sure how this behavior would be accomplished in your library.
