DirectionsLeg interface

google.maps.DirectionsLeg interface

A single leg consisting of a set of steps in a DirectionsResult. Some fields in the leg may not be returned for all requests. Note that though this result is "JSON-like," it is not strictly JSON, as it directly and indirectly includes LatLng objects.

Properties
`end_address`	Type: `string` The address of the destination of this leg. This content is meant to be read as-is. Do not programmatically parse the formatted address.
`end_location`	Type: `LatLng` The `DirectionsService` calculates directions between locations by using the nearest transportation option (usually a road) at the start and end locations. `end_location` indicates the actual geocoded destination, which may be different than the `end_location` of the last step if, for example, the road is not near the destination of this leg.
`start_address`	Type: `string` The address of the origin of this leg. This content is meant to be read as-is. Do not programmatically parse the formatted address.
`start_location`	Type: `LatLng` The `DirectionsService` calculates directions between locations by using the nearest transportation option (usually a road) at the start and end locations. `start_location` indicates the actual geocoded origin, which may be different than the `start_location` of the first step if, for example, the road is not near the origin of this leg.

Version 3.27 will be the last version of the API that adds extra `via_waypoints` in alternative routes. When using the Directions Service to implement draggable directions, it is recommended to disable dragging of alternative routes. Only the main route should be draggable. Users can drag the main route until it matches an alternative route.
`arrival_time optional`	Type: `Time optional` An estimated arrival time for this leg. Only applicable for TRANSIT requests.
`departure_time optional`	Type: `Time optional` An estimated departure time for this leg. Only applicable for TRANSIT requests.
