Implementations

Once we finish this PathStep, how much distance will be crossed? If the step is at the beginning or end of our path, then the full length may not be used.

The original PathRequest used to produce this path. If the path has been modified since creation, the start and end of the request won’t match up with the current path steps.

Trusting the caller to do this in valid ways.

Traces along the path from its originally requested start. This is only valid to call for an umodified path.

It mostly seems the PolyLine’s length will match total_length, but callers beware if you’re relying on this – check walking paths with the buggy sharp angles particularly.

Traces along the path from a specified distance along the first step until the end.

Draws the thickened path, matching entire roads. Ignores the path’s exact starting and ending distance.

Estimate how long following the path will take in the best case, assuming no traffic or delay at intersections. To determine the speed along each step, the agent’s optional max_speed must be known.

If the agent following this path will initially block some intermediate lanes as they move between a driveway and get_req().start, then record them here.

Returns the total elevation (gain, loss) experienced over the path.
