darc - Dynamically-atomic reference-counting pointers

Crate Documentation minimum rustc 1.31

This is a proof of concept of a Rust Rc<T> type that can dynamically choose whether to use atomic access to update its reference count. A related Arc<T> can be created which offers thread-safe (Send + Sync) access to the same data. If there's never an Arc, the Rc never pays the price for atomics.

darc currently requires rustc 1.31.0 or greater.
