Composition

Composition is a new Minecraft server written from the ground-up in Rust.

Composition is targeting Minecraft version 1.19.3, protocol version 761. The main goal is to get a working server, then optimize for speed (multi-threading/kubernetes/etc).

Project Structure

Composition is broken up into multiple crates to speed up build times and improve modularity.

• src/main.rs is a wrapper around composition-core that sets up logging among other things. This is the main binary that is exported with cargo build.
• composition-core implements the main server logic, such as handling clients and loading world chunks.
• composition-protocol handles the types and packets needed for network communication. The library was designed to be able to used by anyone looking to implement a Minecraft server.
• composition-config handles the server configuration files and command line argument parsing.
