fastjson: optimized standard library JSON for Go

fastjson has the same API as json from standard library encoding/json. The Unmarshal and Decode functions are faster, but everything else is the same as encoding/json

Getting Started

$go get github.com/intel-go/fastjson

##Perfomance The performance depends on the content of your json structures, not the structure you parse to. If .json has a lot of strings or numbers, fastjson is significantly faster than encoding/json

##Example

import (
    "github.com/intel-go/fastjson"
    "fmt"
)

func main() {
    var jsonBlob = []byte(`[
	{"Name": "Platypus", "Order": "Monotremata"},
	{"Name": "Quoll",    "Order": "Dasyuromorphia"}
    ]`)
    type Animal struct {
	Name  string
	Order string
    }
    var animals []Animal
    err := fastjson.Unmarshal(jsonBlob, &animals)
    if err != nil {
	fmt.Println("error:", err)
    }
    fmt.Printf("%+v", animals)
    // Output:
    // [{Name:Platypus Order:Monotremata} {Name:Quoll Order:Dasyuromorphia}]
}
