Zero-Copy-Konvertierung von Byte-Slices in Strings mittels unsafe.SliceData und unsafe.String

package main
 
import (
	"fmt"
	"unsafe"
)
 
func FastBytesToString(b []byte) string {
	if len(b) == 0 {
		return ""
	}
	return unsafe.String(unsafe.SliceData(b), len(b))
}
 
func FastStringToBytes(s string) []byte {
	if len(s) == 0 {
		return nil
	}
	return unsafe.Slice(unsafe.StringData(s), len(s))
}
 
func main() {
	buf := []byte("Zero Allocation High Performance String")
	str := FastBytesToString(buf)
	back := FastStringToBytes(str)
 
	fmt.Printf("String: %s, Bytes len: %d\n", str, len(back))
}
