软件介绍

Easyjson用于序列化JSON数据，采用Go语言编写，而不是通过使用反射生成编组代码。一个库的目的之一是使所生成的代码足够简单，使得它可以容易地优化或固定。另一个目标是为用户提供不可定制的“encoding/json”，如产生snake_case名称或启用默认“omitempty“生成代码。

用法：

go get github.com/mailru/easyjson/...
easyjson -all <file>.go

这将利用编组/解组方法结构生成<file>_easyjson.go。

限制：

• The library is at an early stage, there are likely to be some bugs and some features of 'encoding/json' may not be supported. Please report such cases, so that they may be fixed sooner.

• Unsafe package is used by the code. While a non-unsafe version of easyjson can be made in the future, using unsafe package simplifies a lot of code by allowing to use 'switch' for filling out structs and working around limitations of standard functions like 'strconv.ParseInt'.

• Floats are currently formatted with default precision for 'strconv' package. It is obvious that it is not always the correct way to handle it, but there aren't enough use-cases for floats at hand to do anything better.

• During parsing, parts of JSON that are skipped over are not syntactically validated more than required to skip matching parentheses.

• No true streaming support for encoding/decoding. For many use-cases and protocols, data length is typically known on input and needs to be known before sending the data.

编组，one goroutine
