pubsub: SeekToTime missing on upgrade to v2.0.0

Client

PubSub

Expected behavior

google-cloud-go/pubsub/snapshot.go

Line 122 in f59fcff

func (s *Subscription) SeekToTime(ctx context.Context, t time.Time) error {

We used SeekToTime in our old v1 pub/sub code. But it looks like in the v2 branch snapshots were removed.

I don't see any reference to this in the migration docs so i'm not sure if this was intentional or not.

Actual behavior

We'd like to add SeekToTime back

Screenshots

e.g. A chart showing how messages are slow. Delete if not necessary.

Additional context

e.g. Started after upgrading to v2.0.0

Hi,

Thanks for filing an issue. SeekToTime is part of the admin layer which is now offloaded to SubscriptionAdminClient.

Here's an example of how to do this in v2 code. I'll also update our docs to make this more clear.
The main difference is needing to use the pubsubpb (generated pubsub proto types) and timestamppb (proto timestamp type) imports.

projectID := "my-project-id"
subscriptionID := "my-subscription-id"

now := time.Now()

client, _ := pubsub.NewClient(ctx, projectID)
client.SubscriptionAdminClient.Seek(ctx, &pubsubpb.SeekRequest{
	Subscription: fmt.Sprintf("projects/%s/subscriptions/%s", projectID, subID),
	Target: &pubsubpb.SeekRequest_Time{
		Time: timestamppb.New(now),
	},
})

Please continue to file issues for anything that's surprising about the v2.

Ah okay thanks. I didn't see that moved to the admin layer. Thanks!
