Implementations

impl Pathfinder

pub fn empty() -> Pathfinder

Quickly create an invalid pathfinder, just to make borrow checking / initialization order work.

pub fn new(
    map: &Map,
    params: RoutingParams,
    engine: CreateEngine<'_>,
    timer: &mut Timer<'_>
) -> Pathfinder

pub fn new_limited(
    map: &Map,
    params: RoutingParams,
    engine: CreateEngine<'_>,
    modes: Vec<PathConstraints>,
    timer: &mut Timer<'_>
) -> Pathfinder

Create a new Pathfinder with custom routing params that can only serve some modes.

pub fn pathfind(&self, req: PathRequest, map: &Map) -> Option<PathV2>

Finds a path from a start to an end for a certain type of agent.

pub fn pathfind_with_params(
    &self,
    req: PathRequest,
    params: &RoutingParams,
    cache_custom: PathfinderCaching,
    map: &Map
) -> Option<PathV2>

Finds a path from a start to an end for a certain type of agent. May use custom routing parameters. If caching is requested and custom routing parameters are used, then the intermediate graph is saved to speed up future calls with the same routing parameters.

pub fn clear_custom_pathfinder_cache(&self)

pub fn all_costs_from(
    &self,
    req: PathRequest,
    map: &Map
) -> Option<(Duration, HashMap<DirectedRoadID, Duration>)>

pub fn should_use_transit(
    &self,
    map: &Map,
    start: Position,
    end: Position
) -> Option<(TransitStopID, Option<TransitStopID>, TransitRouteID)>

pub fn apply_edits(&mut self, map: &Map, timer: &mut Timer<'_>)
