Functions

func BytesFrom

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

func FuncAddr

func FuncAddr(f interface{}) unsafe.Pointer

func GrowSlice

func GrowSlice(s interface{}, cap int)

func IsPtr

func IsPtr(t *GoType) bool

func MapClear

func MapClear(m interface{})

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 StringFrom

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