A library for building RoBust RollBack-based networked games.
rbrb is heavily inspired by GGPO and
GGRS, but aims to be more reliable and capable.
This library assumes your game is a deterministic Fn(&State, Set<Input>) -> State.
We (will) have an additional testing mode that will spend extra cycles on checking that the
state is consitent between players and deterministic on the same logical update.
