Is there a library function to convert a []byte into a struct? I'm working on a client to catch a struct sent from a server written in C.
I have my struct setup like this.
type mystruct struct {
A uint32
B uint16
}
This is how I read the bytes over the wire.
var s []byte = make([]byte, 6)
sock.ReadFromUDP(s)
fmt.Println(s)
You could use encoding/binary. From the documentation's example: http://golang.org/pkg/encoding/binary/
package main
import (
"bytes"
"encoding/binary"
"fmt"
)
func main() {
var pi float64
b := []byte{0x18, 0x2d, 0x44, 0x54, 0xfb, 0x21, 0x09, 0x40}
buf := bytes.NewReader(b)
err := binary.Read(buf, binary.LittleEndian, &pi)
if err != nil {
fmt.Println("binary.Read failed:", err)
}
fmt.Print(pi)
}
Specifically with structs, it would be something like this.
type mystruct struct {
A uint32
B uint16
}
// ... networking code...
var buff []byte = make([]byte, 6)
sock.ReadFromUDP(buff)
var reader = bytes.NewReader(buff)
var str mystruct
binary.Read(reader, binary.LittleEndian, &str)
// now str has things
fmt.Println(str.A)
