Types

type Eface

type Eface = eface

func ToEface

func ToEface(i Iface) Eface

ToEface converts an iface to an eface.

type FuncType

type FuncType = abi.FuncType

func Func

func Func(in, out []*Type, variadic bool) *FuncType

Func returns a function type.

type Iface

type Iface = iface

type Imethod

type Imethod = abi.Imethod

type InterfaceType

type InterfaceType = abi.InterfaceType

func Interface

func Interface(pkgPath, name string, methods []Imethod) *InterfaceType

Interface returns an interface type. Don't call NewNamed for named interface type.

type Itab

type Itab = itab

func NewItab

func NewItab(inter *InterfaceType, typ *Type) *Itab

NewItab returns a new itab.

type Kind

type Kind = abi.Kind

type Map

type Map = hmap

Map represents a Go map.

func MakeSmallMap

func MakeSmallMap() *Map

MakeSmallMap creates a new small map.

type Method

type Method = abi.Method

type Slice

type Slice struct {
	// contains filtered or unexported fields
}

Slice is the runtime representation of a slice.

func NewSlice3

func NewSlice3(base unsafe.Pointer, eltSize, cap, i, j, k int) (s Slice)

func SliceAppend

func SliceAppend(src Slice, data unsafe.Pointer, num, etSize int) Slice

type String

type String struct {
	// contains filtered or unexported fields
}

String is the runtime representation of a string. It cannot be used safely or portably and its representation may change in a later release.

Unlike reflect.StringHeader, its Data field is sufficient to guarantee the data it references will not be garbage collected.

	// contains filtered or unexported fields
}
