Protocol Buffers

Protocol Buffers (Protobuf) 是一種序列化資料結構的協定。

對於透過管道(pipeline)或儲存資料進行通訊的程式開發上是很有用的。

這個方法包含一個介面描述語言，描述一些資料結構，並提供程式工具根據這些描述產生程式碼，用於將這些資料結構產生或解析資料串流。

Language support

Protobuf 2.0 provides a code generator for C++, Java, C#, and Python.

Third-party implementations are also available for JavaScript.

Protobuf 3.0 provides a code generator for C++, Java (including JavaNano, a dialect intended for low-resource environments), Python, Go, Ruby, Objective-C, C#. It also supports JavaScript since 3.0.0-beta-2.

Protobuf 4.0 is largely the same as 3.0 but the C extension for PHP being rewritten, dropping support for PHP 5.

Third-party implementations are also available for C, Dart, Haskell, Perl, PHP, R, Rust, Scala, Swift, Julia and Nim.
