This library provides a simple replacement for when std::shared_ptrs are not
suitable. Rc stands for "reference counted" (very creative, I know), inspired by Rust's
Arc. The API is similar to that of std::shared_ptr and std::weak_ptr.
Rc has two main selling points.
One, both pointer types are non atomic (saving some of the associated overhead)--and thus not thread safe!
Second, both pointer types (rc andweak_rc) are the size of
the architecture's word size (i.e. equal to sizeof(void*). Besides saving space, this allows rc pointers to be passed
to C style functions that take a void* as their generic parameter. To faciliatate
this, special conversion methods are provided to cast to void* and to
reconstruct rc pointers from void*.
USE AT YOUR OWN RISK! This library has not been thoroughly tested, it's a recent experiment that needs further evaluation.
