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 IndexCharUint ¶ added in v0.5.2

func IndexCharUint(src string, index int) uintptr

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 uintptr, b uintptr) int

func Str2Mem ¶

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

func StrBoundary ¶ added in v0.5.2

func StrBoundary(src string) uintptr

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
