Struct map_model::PathV2

pub struct PathV2 {
    steps: Vec<PathStepV2>,
    req: PathRequest,
    cost: Duration,
    uber_turns: Vec<UberTurnV2>,
}

A path between two endpoints for a particular mode. This representation is immutable and doesn’t prescribe specific lanes and turns to follow.

Fields

steps: Vec<PathStepV2>

req: PathRequest

cost: Duration

uber_turns: Vec<UberTurnV2>

Implementations

impl PathV2

pub(crate) fn new(
    steps: Vec<PathStepV2>,
    req: PathRequest,
    cost: Duration,
    uber_turns: Vec<UberTurnV2>
) -> PathV2

pub fn from_roads(
    roads: Vec<DirectedRoadID>,
    req: PathRequest,
    cost: Duration,
    uber_turns: Vec<UberTurnV2>,
    map: &Map
) -> PathV2

Vehicle implementations often just calculate the sequence of roads. Turn that into PathStepV2 here.

pub fn get_req(&self) -> &PathRequest

The original PathRequest used to produce this path.

pub fn get_steps(&self) -> &Vec<PathStepV2>

All steps in this path.

pub fn get_cost(&self) -> Duration

The time needed to perform this path. This time is not a lower bound; physically following the path might be faster. This time incorporates costs like using sub-optimal lanes or taking difficult turns.

pub fn into_v1(self, map: &Map) -> Result<Path>

Transform a sequence of roads representing a path into the current lane-based path, by picking particular lanes and turns to use.

fn into_v1_walking(self, map: &Map) -> Result<Path>

pub fn crosses_road(&self, r: RoadID) -> bool

pub fn trace_v2(&self, map: &Map) -> Result<Polygon>

Draws the thickened path, matching entire roads. Ignores the path’s exact starting and ending distance. Doesn’t handle contraflow yet.

pub fn trace_all_polygons(&self, map: &Map) -> Vec<Polygon>

Returns polygons covering the entire path. Ignores the path’s exact starting and ending distance.
