[Warning WIP] 1.20.4 Minecraft server written in Rust

Minecraft server (made with Rust)

It is a project that eliminates the necessary hardware performance cost and optimizes the server from the bottom without the economic difficulty of purchasing expensive hosting servers to operate Minecraft servers

Why do I have to start this project and make something new

No Minecraft server existed that satisfies the requirements below.

Project Requirements

• In Raspberry Pi Zero 2W (ARM Cortex A53 processor clocked at 1GHz and 512MB RAM) environments, high performance server applications are required to hold more than 30 users
• Different versions of clients connect to a server
• AntiCheat
• Various minigames

Discussion

Things that I need to think about more and make sure to decide

• A client for testing shall be implemented.
• Pluggable selector pattern design structure or ECS (Entity Component System) structure

things that have already been carefully decided in the project

• Implement Minecraft Server as Rust
• Let's use the mio crate, without having to implement the socket selector kqueue/epoll directly

Why did you choose Rust Language

• None of the servers originally made in the Java language had the performance I wanted.
• Java is slow. It takes as much as 7 nanoseconds to create a single buffer. (It was slower than Rust, which takes up to 1 nanosecond at its best performance.)
• The reason for choosing Rust over C/C++ is that Rust has a more powerful type system than Java/Kotlin.

Why use the standard library's buffer Cursor<Vec> without using the BytesMut of bytes crate
