🌵 CactusRef lets you build cyclic data structures using strong references
and knows how to deallocate unreachable cycles. You can use CactusRef to
implement a doubly linked list. The CactusRef API is compatible with std::rc.
To learn Rust, I implemented an audio game. There were some things I
liked and some things I didn't. Some things were easy and some were hard. And
there were plenty of libraries that were a joy to use.
