	Callback func(event *PluginEvent) error
}

PluginEventHandler 触发插件事件的回调

type PluginEventType

type PluginEventType int

PluginEventType .

const (
	// OnInstanceLocalValueCreated 本地缓存实例创建后触发的时机
	OnInstanceLocalValueCreated PluginEventType = 0x8001
	// OnContextStarted 在所有插件创建完毕后触发的事件
	OnContextStarted PluginEventType = 0x8002
	// OnServiceAdded sdk内存中添加了一个服务(实例或路由)触发的事件
	OnServiceAdded PluginEventType = 0x8003
	// OnServiceUpdated sdk内存中更新了一个服务(实例或路由)触发的事件
	OnServiceUpdated PluginEventType = 0x8004
	// OnServiceDeleted sdk内存中删除了一个服务(实例或路由)触发的事件
