type Instance interface {
	Id() string
	Addr() string
	Weight() uint32
	Tags() map[string]string
}

func NewInstance(id, addr string, weight uint32, tags map[string]string) Instance

type Resolver interface {
	Name() string
	Resolve(ctx context.Context, service string) (*Result, error)
	Close() error
}

Resolver 用于解析service

可以是基于registry的服务发现
也可以是基于DNS的域名解析
或者返回固定IP

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

func NewResult(instances []Instance) *Result

func (r *Result) Empty() bool

func (r *Result) HashCode() uint32

func (r *Result) Instances() []Instance

func (r *Result) Len() int

func (r *Result) Remove(id string)

func (r *Result) SetInstances(ins []Instance)

func (r *Result) Upsert(ins Instance)
