Functions

func AddPtr

func AddPtr(a unsafe.Pointer, b uintptr) unsafe.Pointer

func BytesFrom

func BytesFrom(p unsafe.Pointer, n int, c int) (r []byte)

func Get16

func Get16(v []byte) int16

func Get32

func Get32(v []byte) int32

func Get64

func Get64(v []byte) int64

func GetBytePtr

func GetBytePtr(b []byte) unsafe.Pointer

func GuardSlice

func GuardSlice(buf *[]byte, n int)

func IndexByte

func IndexByte(ptr *[]byte, index int) unsafe.Pointer

func IndexChar

func IndexChar(src string, index int) unsafe.Pointer

func IndexPtr

func IndexPtr(ptr unsafe.Pointer, size uintptr, index int) unsafe.Pointer

func IndexSlice

func IndexSlice(slice unsafe.Pointer, size uintptr, index int) unsafe.Pointer

func Mem2Str

func Mem2Str(v []byte) (s string)

func NoEscape

func NoEscape(p unsafe.Pointer) unsafe.Pointer

NoEscape hides a pointer from escape analysis. NoEscape is the identity function but escape analysis doesn't think the output depends on the input. NoEscape is inlined and currently compiles down to zero instructions. USE CAREFULLY!

func PackInt

func PackInt(v int) uint64

func PtrOffset

func PtrOffset(a unsafe.Pointer, b unsafe.Pointer) int

func Str2Mem

func Str2Mem(s string) (v []byte)

func StringFrom

func StringFrom(p unsafe.Pointer, n int) (r string)

func SubPtr

func SubPtr(a unsafe.Pointer, b uintptr) unsafe.Pointer

func UnpackInt

func UnpackInt(v uint64) int
