A Rust implementation of the RakNet protocol, a reliable UDP transport for game networking and Minecraft Bedrock Edition.
rust-raknet is a Rust library that implements the RakNet protocol, a reliable UDP transport layer designed for real-time network communication. It provides better performance than TCP in unstable network conditions and is specifically engineered for interoperability with Minecraft Bedrock Edition. The library offers various reliability modes and performance optimizations to reduce latency in lossy network environments.
Rust developers building real-time multiplayer game servers or clients, particularly those working with Minecraft Bedrock Edition or other applications requiring reliable UDP communication. It also targets developers needing a high-performance alternative to TCP for networked applications in unstable network conditions.
Developers choose rust-raknet for its pure Rust implementation with no external dependencies, built-in compatibility with Minecraft Bedrock Edition, and performance optimizations like fast retransmission and non-delayed ACK that reduce latency by up to 50% compared to TCP in high packet loss scenarios. Its asynchronous support via Tokio 1.x makes it suitable for modern Rust applications.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Benchmarks show up to 50% lower latency than TCP under 50% packet loss, due to optimizations like fast retransmission and non-delayed ACK, as highlighted in the README.
Specifically engineered to interoperate with Minecraft Bedrock Edition, enabling custom server development without client modifications, per the project description.
No external dependencies beyond Rust's ecosystem, ensuring memory safety and easy integration for Rust projects, as stated in the features.
Supports five reliability options including unreliable, reliable ordered, and sequenced transmissions, providing fine-grained control for real-time applications.
The README admits it's an incomplete implementation through reverse engineering, which may result in missing features, bugs, or compatibility issues with official RakNet.
Focused primarily on game networking and Minecraft, it lacks the broad community support, documentation, and third-party tools available for standard networking libraries.
Requires Tokio 1.x asynchronous runtime, making it unsuitable for projects using other async runtimes or synchronous architectures without significant refactoring.
