package encoding/hex
Encode encodes src(2nd parameter) into EncodedLen(len(src)) bytes of dst (1st parameter). As a convenience, it returns the number of bytes written to dst, but this value is always EncodedLen(len(src)). Encode implements hexadecimal encoding.
Golang encoding/hex.Encode() function usage example
package main
import (
"encoding/hex"
"fmt"
)
func main() {
str := "abcdef"
src := []byte(str)
dst := make([]byte, hex.EncodedLen(len(src)))
num := hex.Encode(dst, src)
fmt.Printf("Number of bytes written : %v \n", num)
}
Output :
Number of bytes written : 12
