The OP does not seem to mention CactusRef https://crates.io/crates/cactusref which provides deterministic deallocation (on par with simple refcounting) of reference cycles, with minimal tracing requirements and minimal memory overhead.

Probably because cactusref was only published 5 days ago and this article is from three months ago...

It used to require unsafe. The project has been reworked to add safer alternatives (at the cost of some increased overhead).
