Functions ¶

func Compare8 ¶

func Compare8(a, b unsafe.Pointer) int

func Compare16 ¶

func Compare16(a, b unsafe.Pointer) int

func Compare32 ¶

func Compare32(a, b unsafe.Pointer) int

func Compare64 ¶

func Compare64(a, b unsafe.Pointer) int

func Compare128 ¶

func Compare128(a, b unsafe.Pointer) int

func Eface2Interface ¶

func Eface2Interface(eface Eface) interface{}

func GetCompare ¶

func GetCompare(a, b unsafe.Pointer, size uintptr) func(a, b unsafe.Pointer) int

func IsDirectIface ¶

func IsDirectIface(t *Type) bool

IsDirectIface reports whether t is stored directly in an interface value.

func Noescape ¶

func Noescape(p unsafe.Pointer) unsafe.Pointer

copy from package runtime 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 NoescapeInterface ¶

func NoescapeInterface(x interface{}) interface{}

func UnsafeAlloc ¶

func UnsafeAlloc(size uintptr) unsafe.Pointer

Types ¶

type Eface ¶

type Eface struct {
	Type *Type
	Data unsafe.Pointer
}

func EfaceOf ¶

func EfaceOf(eface interface{}) Eface

type Iface ¶

type Iface struct {
	Tab  *itab
	Data unsafe.Pointer
}

type Slice ¶

type Slice struct {
	Array unsafe.Pointer
	Len   int
	Cap   int
}

type String ¶

type String struct {
	Str unsafe.Pointer
	Len int
}

type Type ¶

type Type struct {
	Size uintptr

	Kind uint8
	// contains filtered or unexported fields
}

Needs to be in sync with ../cmd/link/internal/ld/decodesym.go:/^func.commonsize, ../cmd/compile/internal/gc/reflect.go:/^func.dcommontype and ../reflect/type.go:/^type.rtype.

func TypeOf ¶

func TypeOf(eface interface{}) *Type
