+# rocketmq-rust
+
+Rocketmq非官方的Rust实现
+
+## 模块
+
+现有的Rocketmq主要有如下几个功能模块：
+
+- **Name Server**
+- **Broker**
+- **Store(存储-本地)**
+- **Controller(高可用)**
+- **Client(SDK)**
+- **Proxy(代理)**
+- **Tiered store(分级存储模块)**
+
+每个模块的具体作用可以参照[Rocketmq的官方说明文档](https://github.com/apache/rocketmq/tree/develop/docs) 。Rust的实现会根据下面的顺序逐一来进行实现。
+
+## Name Server
+
+### Broker管理
+
+- [ ] [WIP]Broker注册
+- [ ] HeartBeat消息处理
+
+TODO
+
+后续会进行其他的模块实现，首先会对NameServer进行Rust实现，目标是能够达到和Java版本一样的功能。

-# rocketmq-rust
+# rocketmq-rust
+
+Unofficial Rust implementation of RocketMQ.
+
+## Modules
+
+The existing RocketMQ has the following functional modules:
+
+- **Name Server**
+- **Broker**
+- **Store (Local Storage)**
+- **Controller (High Availability)**
+- **Client (SDK)**
+- **Proxy**
+- **Tiered Store (Tiered Storage Module)**
+
+The specific functions of each module can be referred to in the [official RocketMQ documentation](https://github.com/apache/rocketmq/tree/develop/docs). The Rust implementation will be carried out sequentially in the following order.
+
+## Name Server
+
+### Broker Management
+
+- [ ] **[WIP] Broker registration**
+- [ ] **Heartbeat message processing**
+
+TODO
+
+Other module implementations will be done subsequently, starting with the Rust implementation of the Name Server. The goal is to achieve functionality similar to the Java version.
