## Enumeration Type Documentation

enum EndSegmentReason

Enumerator:

  ESR_DEAD_END | track ends here
  ESR_RAIL_TYPE | the next tile has a different rail type than our tiles
  ESR_INFINITE_LOOP | infinite loop detected
  ESR_SEGMENT_TOO_LONG | the segment is too long (possible infinite loop)
  ESR_CHOICE_FOLLOWS | the next tile contains a choice (the track splits to more than one segments)
  ESR_DEPOT | stop in the depot (could be a target next time)
  ESR_WAYPOINT | waypoint encountered (could be a target next time)
  ESR_STATION | station encountered (could be a target next time)
  ESR_SAFE_TILE | safe waiting position found (could be a target)
  ESR_PATH_TOO_LONG | the path is too long (searching for the nearest depot in the given radius)
  ESR_FIRST_TWO_WAY_RED | first signal was 2-way and it was red
  ESR_LOOK_AHEAD_END | we have just passed the last look-ahead signal
  ESR_TARGET_REACHED | we have just reached the destination
  ESR_NONE | no reason to end the segment here
