Easyjson快速JSON序列化

Easyjson用于序列化JSON數(shù)據(jù)，采用Go語(yǔ)言編寫，而不是通過(guò)使用反射生成編組代碼。一個(gè)庫(kù)的目的之一是使所生成的代碼足夠簡(jiǎn)單，使得它可以容易地優(yōu)化或固定。另一個(gè)目標(biāo)是為用戶提供不可定制的“encoding/json”，如產(chǎn)生snake_case名稱或啟用默認(rèn)“omitempty“生成代碼。

用法：

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

這將利用編組/解組方法結(jié)構(gòu)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.
