More idiomatic way in Go to encode a []byte slice int an int64?

Question

Is there a better or more idiomatic way in Go to encode a []byte slice into an int64?

package main

import \"fmt\"

func main() {
    var mySlice = []byte{244, 2         


        

Answer 1

I'm not sure about idiomatic, but here's an alternative using the encoding/binary package:

package main

import (
   "bytes"
   "encoding/binary"
   "fmt"
)

func main() {
   var mySlice = []byte{244, 244, 244, 244, 244, 244, 244, 244}
   buf := bytes.NewReader(mySlice)
   var data int64
   err := binary.Read(buf, binary.LittleEndian, &data)
   if err != nil {
      fmt.Println("binary.Read failed:", err)
   }
   fmt.Println(data)
}
