The QGeoRouteSegment class represents a segment of a route.
A QGeoRouteSegment instance has information about the physical layout of the route segment, the length of the route and estimated time required to traverse the route segment and an optional QGeoManeuver associated with the beginning of the route segment.
QGeoRouteSegment instances can be thought of as edges on a routing graph, with QGeoManeuver instances as optional labels attached to the vertices of the graph.
Constructs an invalid route segment object.
The route segment will remain invalid until one of setNextRouteSegment (), setTravelTime (), setDistance (), setPath () 或 setManeuver () 被调用。
Constructs a route segment object from the contents of other .
Destroys this route segment object.

Returns whether this route segment is valid or not.
若 nextRouteSegment () is called on the last route segment of a route, the returned value will be an invalid route segment.
Returns the maneuver for this route segment.
Will return an invalid QGeoManeuver if no information has been attached to the starting point of this route segment.
