How to convert []int8 to string

Question

What\'s the best way (fastest performance) to convert from []int8 to string?

For []byte we could do string(byteslice), but for

Answer 1

What is sure from "Convert between slices of different types" is that you have to build the right slice from your original int8[].

I ended up using rune (int32 alias) (playground), assuming that the uint8 were all simple ascii character. That is obviously an over-simplification and icza's answer has more on that.
Plus the SliceScan() method ended up returning uint8[] anyway.

package main

import (
    "fmt"
)

func main() {
    s := []int8{'a', 'b', 'c'}
    b := make([]rune, len(s))
    for i, v := range s {
        b[i] = rune(v)
    }
    fmt.Println(string(b))
}

But I didn't benchmark it against using a []byte.
