Functions

func IFaceToEFace

func IFaceToEFace(ptr unsafe.Pointer) interface{}

func IsNil

func IsNil(obj interface{}) bool

func IsNullable

func IsNullable(kind reflect.Kind) bool

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 PtrOf

func PtrOf(obj interface{}) unsafe.Pointer

func RTypeOf

func RTypeOf(obj interface{}) uintptr
