Functions

func BytesToString

func BytesToString(bytes []byte) string

BytesToString unsafe convert byte array content to string This function do not allocate new buffer, reuse the bytes data.

func CurrentGoroutineId

func CurrentGoroutineId() int64

CurrentGoroutineId get current goroutine id by walk stack. This func get goroutine id by parse current stack string, the performance is not so good.

func InterfaceIsNil

func InterfaceIsNil(iface interface{}) bool

InterfaceIsNil return true if interface is nil or it's value is a nil pointer

func InterfaceValuePtr

func InterfaceValuePtr(iface interface{}) unsafe.Pointer

InterfaceValuePtr return the value pointer of interface

func StringToBytes

func StringToBytes(str string) []byte

StringToBytes unsafe convert string to byte array This function do not allocate new buffer, reuse the string buffer.

Types

type SliceHeader

type SliceHeader struct {
	Data unsafe.Pointer
	Len  int
	Cap  int
}

SliceHeader copy from reflect.SliceHeader, using Data type unsafe.Pointer instead of unitptr, to prevent stack allocation, or free by gc

type StringHeader

type StringHeader struct {
	Data unsafe.Pointer
	Len  int
}

StringHeader copy from reflect.StringHeader, using Data type unsafe.Pointer instead of unitptr, to prevent stack allocation, or free by gc
