ch	Uses https://github.com/easbar/fast_paths. Slower creation during map importing, but very fast queries.
dijkstra	Pathfinding without needing to build a separate contraction hierarchy.
driving	Pathfinding for cars, bikes, buses, and trains using contraction hierarchies
node_map	Some helpers for working with fast_paths.
uber_turns	To deal with complicated intersections and short roads in OSM, cluster intersections close together and then calculate UberTurns that string together several turns.
walking	Pathfinding for pedestrians using contraction hierarchies, as well as figuring out if somebody should use public transit.

Path
PathRequest

PathConstraints	Who's asking for a path?
PathStep
Pathfinder	Most of the time, prefer using the faster contraction hierarchies. But sometimes, callers can explicitly opt into a slower (but preparation-free) pathfinder that just uses Dijkstra's maneuever.
