# 核心 API 参考文档

## 前言

内容来自 ectd3 的 [API reference](https://github.com/coreos/etcd/blob/master/Documentation/dev-guide/api_reference_v3.md)。

原文内容是从 .proto 文件生成的，service和方法定义/message定义一起构成一个庞大的单页HTML文件，不利于阅读。因此在翻译时，遵循gitbook的习惯，按照服务/方法分开形成章节结构。

主要内容在 message 的字段定义上，翻译时没有复制原文中从 .proto 文件生成的表格，而是直接在 .proto 文件的 message 定义上翻译，感觉更直观一些。
