At time of writing, the public facing API \nis stable, and has undergone limited testing. There may still be notable bugs\nthat have not been found yet.\n\n## Differences with the C++ implementation\n\n * (Almost) 100% pure **safe** Rust. No unsafe pointer manipulation.\n * Type safety. backroll-rs heavily utilizes generics and associated types to \n   avoid serialization overhead and potentially unsafe type conversions when \n   saving and loading game state.\n * Abstracted transport layer protocols - integrate and use any transport layer\n   library you need. Comes with a raw UDP socket based implementation.\n * Configurable at runtime - Many of the hard-coded constants in GGPO are exposed\n   as configuration parameters during session initialization.\n * Reduced memory usage - Backroll's use of generics potentially shrinks down\n   the sizes of many data types.\n * Vectorized input compression scheme - Backroll utilizes the same XOR + RLE\n   encoding, but it's written to maximize CPU utilization.\n * Multithreaded I/O - All network communications run within an async task pool.\n   I/O polling is no longer manual, nor blocks your game's execution.\n\n## Repository Structure\nThis repo contains the following crates:\n\n * backroll - the main Backroll interface, intended to be used as the original\n   GGPO.\n * backroll\\_transport - An isolated set of transport layer abstractions. \n * backroll\\_transport\\_udp - A transport layer implementation using raw UDP\n   sockets. \n * backroll\\_transport\\_steam - A transport layer implementation using the \n   Steam provided networking utilities. Enables access to the Steam Datagram\n   Relay service.\n * bevy\\_backroll - a integration plugin for [bevy](https://bevyengine.org/).\n   (Complete, untested).\n * lib - third-party linking dependencies (i.e. Steam) for easier local \n   development","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fhouraiteahouse%2Fbackroll-rs","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fhouraiteahouse%2Fbackroll-rs","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fhouraiteahouse%2Fbackroll-rs/lists"}
