PacketProcessor

实现数据打包和解包，用于解决数据传输中的粘包等问题。

包头2字节(0x5AA5)+数据净长度4字节(大端序)+长度校验2字节(长度CRC16)+数据+校验2字节(数据CRC16/长度CRC16的按位取反)

Requirements

• C++11
• CMake 3.1

Features

• CRC16 for data length
• CRC16 of data is option (default is data size CRC)
• Only 10 bytes for data header and CRC
• Support packForeach avoid unnecessary data copy

Usage

• simplest

PacketProcessor processor([&](uint8_t* data, size_t size) {
    printf("Got packet: %zu, %s\n", size, std::string((char*)data, size).c_str());
});
auto payload = processor.pack("hello world");
processor.feed(payload.data(), payload.size());
