Detailed Description

Abstract wrapper around weaksum implementations.

This is a polymorphic interface to the different rollsum implementations.

Historically rollsum methods were implemented as static inline functions because they were small and needed to be fast. Now that we need to call different methods for different rollsum implementations, they are getting more complicated. Is it better to delegate calls to the right implementation using static inline switch statements, or stop inlining them and use virtual method pointers? Tests suggest inlined switch statements is faster.
