FromClient make new Client by specified datastore.Client.

func FromContext

func FromContext(ctx context.Context, opts ...w.ClientOption) (w.Client, error)

)

const ProjectID = "datastore-wrapper"

func main() {
	ctx := context.Background()
	client, err := clouddatastore.FromContext(
		ctx,
		datastore.WithProjectID(ProjectID),
	)
	if err != nil {
		panic(err)
	}
	defer client.Close()
	defer testutils.CleanUpAllEntities(ctx, client)

	type Data struct {
		Name string
	}

	key := client.IncompleteKey("Data", nil)
	entity := &Data{Name: "mercari"}
	key, err = client.Put(ctx, key, entity)
	if err != nil {

	}

	entity = &Data{}
