Hello gopher's, I have simple go program which convert slice of one type to slice of other type using go generics for handling all the supported types. Below is the code snippest for this: package main
import "fmt" import "unsafe" type slice struct { ptr unsafe.Pointer len int cap int } func Slice[To, From any](data []From) []To { var zf From var zt To var s = (*slice)(unsafe.Pointer(&data)) s.len = int((uintptr(s.len) * unsafe.Sizeof(zf)) / unsafe.Sizeof(zt)) s.cap = int((uintptr(s.cap) * unsafe.Sizeof(zf)) / unsafe.Sizeof(zt)) x := ([]To)(unsafe.Pointer(s)) return x } func main() { a := make([]uint32, 4, 13) a[0] = 1 a[1] = 0 a[2] = 2 a[3] = 0 // 1 0 2 0 b := Slice[int64](a) //Expecxted : []int64[]{0x00000000 00000001, 0x00000000 00000002} //Got: []int64{0x00000001 00000000, 0x00000002 0000000} if b[0] != 1 { fmt.Printf("wrong value at index 0: want=1 got=0x%x \n", b[0]) } if b[1] != 2 { fmt.Printf("wrong value at index 1: want=2 got=0x%x\n", b[0]) } } This is working fine on little endian architectures(amd64,arm64 etc), but when i run on big endian machine(s390x) it is not working , it is resulting wrong data //Expecxted : []int64[]{0x00000000 00000001, 0x00000000 00000002} //Got: []int64{0x00000001 00000000, 0x00000002 0000000} Can somepoint point me how do we write such scenario which should work on both little/endian platforms. Any leads on this? Thanks, Srinivas -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
