//! A library for building RoBust RollBack-based networked games.
//!
//! `rbrb` is heavily inspired by [GGPO](https://www.ggpo.net/) and
//! [GGRS](https://github.com/gschup/ggrs), but aims to be more reliable and capable.
//!
//! # Assumptions
//!
//! 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.
//!
//! # Roadmap
//!
//! ## Core Functionality
//!
//! - [ ] Multi-party sync
//! - [ ] Consistent disconnection
//! - [ ] Reconnect disconnected player
//!
//! ## Robustness
//!
//! - [ ] Determinism checks
//! - [ ] Checksum propagation
//! - [ ] Debugging failed checks
//! - [ ] Fake a bad network
//! - [ ] Confirmation state
//!
//! ## Features
//!
//! - [ ] In-game replays
//! - [ ] Out of game replays
//!   - [ ] Headless
//! - [ ] Spectators
//!   - [ ] Drop in/out
//!
//! ## Performance
//!
//! - [ ] Input delta encoding
//! - [ ] Hub and spoke network
