SliceCap returns the capacity of a slice.

func SliceData

func SliceData(s Slice) unsafe.Pointer

SliceData returns the data pointer of a slice.

func SliceLen

func SliceLen(s Slice) int

SliceLen returns the length of a slice.

func StringData

func StringData(s String) unsafe.Pointer

StringData returns the data pointer of a string.

func StringLen

func StringLen(s String) int

Types

type Interface

type Interface = iface

func MakeAny

func MakeAny(typ *Type, data unsafe.Pointer) Interface

func MakeAnyInt

func MakeAnyInt(typ *Type, data uintptr) Interface

func MakeAnyString

func MakeAnyString(data string) Interface

func MakeInterface

func MakeInterface(inter *InterfaceType, typ *Type, data unsafe.Pointer) Interface

type InterfaceType

type InterfaceType = abi.InterfaceType

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 Slice

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

Slice is the runtime representation of a slice.

func NewSlice

func NewSlice(data unsafe.Pointer, len, cap int) Slice

NewSlice creates a new slice.

func NewSlice3

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

func NilSlice

func NilSlice() Slice

NilSlice returns a nil 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.

func EmptyString

func EmptyString() String

EmptyString returns an empty string.

func NewString

func NewString(data unsafe.Pointer, len int) String

NewString creates a new string.

func NewStringSlice

func NewStringSlice(base String, i, j int) String

func StringCat

func StringCat(a, b String) String

StringCat concatenates two strings.

type Type

type Type = abi.Type

func Basic

func Basic(kind Kind) *Type
