TollStopWarningDelegate
public protocol TollStopWarningDelegate : AnyObject
This protocol should be implemented in order to receive information on the upcoming toll booth structure.
The warner might also warn about gates/checkpoints for vignette, border checkpoints and similar structures on the street.
Note: This is a beta release of this feature, so there could be a few bugs and unexpected
behaviors. Related APIs may change for new releases without a deprecation process.
A TollStop will not be given until the previous warning of that type has been passed.
For example, a route with TollStop 120 meters and TollStop 160 meters ahead,
the first TollStop.distance_to_toll_stop_in_meters is 120 meters
and the next TollStop.distance_to_toll_stop_in_meters is then 40 meters,
since that is the distance between the first and second warnings.
