Package replication handles fetching the Minute, Hour, Day and Changeset replication
and the associated state value from Planet OSM.
For example, to fetch the current Minute replication state:
num, fullState, err := replication.CurrentMinuteState(ctx)This is the data in http://planet.osm.org/replication/minute/state.txt updated every minute.
Once you know the change number you want, fetch the change using:
change, err := replication.Minute(ctx, num)It's also possible to find the sequence number by timestamp. These calls make multiple requests for state to find the one matching the given timestamp.
MinuteStateAt(ctx context.Context, timestamp time.Time) (MinuteSeqNum, *State, error)
HourStateAt(ctx context.Context, timestamp time.Time) (HourSeqNum, *State, error)
DayStateAt(ctx context.Context, timestamp time.Time) (DaySeqNum, *State, error)
ChangesetStateAt(ctx context.Context, timestamp time.Time) (ChangesetSeqNum, *State, error)
