Types

type Chan

type Chan struct {
	QueueCount    uint           // total data in the queue
	DataQueueSize uint           // size of the circular queue
	Buf           unsafe.Pointer // points to an array of dataqsiz elements
	ElemSize      uint16
	Closed        uint32
}

Chan for go channel

type Interface

type Interface struct {
	Type  unsafe.Pointer
	Value unsafe.Pointer
}

Interface having same structure with go interface

type Mutex

type Mutex struct {
	State int32
	Sema  uint32
}

Mutex copy from sync.Mutex

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
