Lib.rs

cbsk是一个TCP数据回调工具，允许您专注于业务处理，无需担心TCP数据的读取、写入和拆分

支持Rust的最小版本

1.80.0

内部协议

cbsk内部有一个自定义的TCP数据验证协议，其协议逻辑如下

1. 验证数据是否使用['c ',' b ','s',' k ']作为头部帧。如果不是，则丢弃数据。当然，您也可以自定义数据帧头部

2. 获取头部帧之后的第一个字节，该字节代表数据长度的描述

3. 根据数据长度的描述获取真实数据长度

4. 读取真实数据，如果有数据包占用，则拆分并调用回调。如果长度不足，则等待下一个TCP数据到达，直到长度一致

5. 重复上述步骤，并重新开始第一个步骤
