Protocol Buffers 是一种轻便高效的结构化数据存储格式,可以用于结构化数据串行化,或者说序列化。它很适合做数据存储或 RPC 数据交换格式。可用于通讯协议、数据存储等领域的语言无关、平台无关、可扩展的序列化结构数据格式。目前提供了 C++、Java、Python三种语言的API。 Protobuf 性能 封解包速度对比,来自网络 Proto...
目前提供了 C++、Java、Python 三种语言的 API。 或许您和我一样,在第一次看完这些介绍后还是不明白 Protobuf 究竟是什么,那么我想一个简单的例子应该比较有助于理解它。 回页首 一个简单的例子 安装Google Protocol Buffer 在网站http://code.google.com/p/protobuf/downloads/list上可以下载 Protobuf 的源代...

在一个varint中的每个字节, 除了最后一个字节外, 有设置有most significant bit (msb) - The lower 7 bits of each byte are used to store the two's complement representation of the number in groups of 7 bits, least significant group first. (该怎么翻译?) ...
Format characters have the following meaning; the conversion between C and Python values should be obvious given their types. The ‘Standard size’ column refers to the size of the packed value in bytes when using standard size; that is, when the format string starts with one of'<','>',...
