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

func (v ByteView) ByteSlice() []byte

func (v ByteView) Len() int

func (v ByteView) String() string

type Getter interface {
	Get(key string) ([]byte, error)
}

type GetterFunc func(key string) ([]byte, error)

实现Getter接口

func (f GetterFunc) Get(key string) ([]byte, error)

定义一个函数类型 F，并且实现接口 A 的方法，然后在这个方法中调用自己。这是 Go 语言中将其他函数（参数返回值定义与 F 一致）转换为接口 A 的常用技巧。

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

核心数据结构

func GetGroup(name string) *Group

func NewGroup(name string, cacheBytes int64, getter Getter) *Group

func (g *Group) Get(key string) (ByteView, error)

func (g *Group) RegisterPeers(peers PeerPicker)

注册节点选择器

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

func NewHTTPPool(self string) *HTTPPool

func (p *HTTPPool) Log(format string, v ...interface{})

func (p *HTTPPool) PickPeer(key string) (PeerGetter, bool)

func (p *HTTPPool) ServeHTTP(w http.ResponseWriter, r *http.Request)

func (p *HTTPPool) Set(peers ...string)

实现PeerPicker接口

type PeerGetter interface {
	Get(in *pb.Request, out *pb.Response) error
}

type PeerPicker interface {
	PickPeer(key string) (peer PeerGetter, ok bool)
}
