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

It's almost overkill to use binary.BigEndian, since it's such a tiny amount of code, and there's some clarity gained by being able to see exactly what's going on. But this is a highly contentious opinion, so your own taste and judgement may differ.

func main() {
    var mySlice = []byte{123, 244, 244, 244, 244, 244, 244, 244}
    data := uint64(0)
    for _, b := range mySlice {
        data = (data << 8) | uint64(b)
    }
    fmt.Printf("%x\n", data)
}
