Types

type Endpoint

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

Endpoint 网关端点

func NewEndpoint

func NewEndpoint(name, address string, options ...EndpointOption) *Endpoint

NewEndpoint 创建网关端点

func (*Endpoint) Connect

func (slf *Endpoint) Connect()

Connect 连接端点

func (*Endpoint) Offline

func (slf *Endpoint) Offline()

Offline 离线

func (*Endpoint) Write

func (slf *Endpoint) Write(packet server.Packet)

Write 写入数据

type EndpointManager

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

EndpointManager 网关端点管理器

func NewEndpointManager

func NewEndpointManager() *EndpointManager

NewEndpointManager 创建网关端点管理器

func (*EndpointManager) AddEndpoint

func (slf *EndpointManager) AddEndpoint(endpoint *Endpoint) error

AddEndpoint 添加端点

func (*EndpointManager) GetEndpoint

func (slf *EndpointManager) GetEndpoint(name string, conn *server.Conn) (*Endpoint, error)

func WithEndpointStateEvaluator

func WithEndpointStateEvaluator(evaluator func(costUnixNano float64) float64) EndpointOption

WithEndpointStateEvaluator 设置端点健康值评估函数

type Gateway

type Gateway struct {
	*EndpointManager // 端点管理器
	// contains filtered or unexported fields
}

Gateway 网关

func NewGateway

func NewGateway(srv *server.Server, options ...Option) *Gateway
