sure

-- import "github.com/anikhasibul/sure"

Package sure helps you to use interfaces with more confidence. It returns zero value when the confidence is not so good.

It helps you to code like this:

if sure.Bool(value){
    //..
} 

instead of

if v,ok := value.(bool); ok {

    //...

}

With sure:

var v = sure.Int(anInterface)

Without sure:

var (

    v int
    ok bool

) 
v, ok = anInterface.(int) if !ok {

    // hndle zero value

} 
// use `v` 

Usage

var PanicWhenWrong = false

PanicWhenWrong - when true it panics when the interface doesn't match with the prefered type. Default is false

func Bool

func Bool(value interface{}) bool

Bool returns bool

func Float32

func Float32(value interface{}) float32

Float32 returns float32

func Float64

func Float64(value interface{}) float64

Float64 returns float64

func HasSet

func HasSet(value interface{}) bool

HasSet returns false if the interface is nil

func Int

func Int(value interface{}) int

Int returns int

func Int64

func Int64(value interface{}) int64

Int64 returns int64

func String

func String(value interface{}) string

String returns string
