Storage Event

一、这是什么

把Storage和events结合，为Storage增加可观测性和安全执行功能。

二、安装依赖

go get -u github.com/storage-lock/go-storage-events

三、组件介绍

WithEventSafeExecutor

为Storage增加可观测性和安全执行功能

四、使用示例

package main

import (
	"context"
	"fmt"
	"github.com/golang-infrastructure/go-iterator"
	"github.com/storage-lock/go-events"
	"github.com/storage-lock/go-storage"
	storage_events "github.com/storage-lock/go-storage-events"
	"time"
)

type FooStorage struct {
}

var _ storage.Storage = &FooStorage{}

func (x *FooStorage) GetName() string {
	//TODO implement me
	panic("implement me")
}

func (x *FooStorage) Init(ctx context.Context) error {
	//TODO implement me
	panic("implement me")
}

func (x *FooStorage) UpdateWithVersion(ctx context.Context, lockId string, exceptedVersion, newVersion storage.Version, lockInformation *storage.LockInformation) error {
	//TODO implement me
	panic("implement me")
}

func (x *FooStorage) CreateWithVersion(ctx context.Context, lockId string, version storage.Version, lockInformation *storage.LockInformation) error {
	//TODO implement me
	panic("implement me")
}

func (x *FooStorage) DeleteWithVersion(ctx context.Context, lockId string, exceptedVersion storage.Version, lockInformation *storage.LockInformation) error {
	//TODO implement me
	panic("implement me")
}

func (x *FooStorage) Get(ctx context.Context, lockId string) (string, error) {
	//TODO implement me
	panic("implement me")
}

func (x *FooStorage) GetTime(ctx context.Context) (time.Time, error) {
	//TODO implement me
	panic("implement me")
}

func (x *FooStorage) Close(ctx context.Context) error {
	//TODO implement me
	panic("implement me")
}

func (x *FooStorage) List(ctx context.Context) (iterator.Iterator[*storage.LockInformation], error) {
	//TODO implement me
	panic("implement me")
}

func main() {
	storage := &FooStorage{}
	executor := storage_events.NewWithEventSafeExecutor(storage)

	event := events.NewEvent("foo").AddListeners(events.NewListenerWrapper("", func(ctx context.Context, e *events.Event) {
		fmt.Print(e.ToJsonString())
	}))
	getTime, err := executor.GetTime(context.Background(), event)
	if err != nil {
		panic(err)
	}
	fmt.Println(getTime)
	// Output:
