Struct map_model::Turn

source ·
pub struct Turn {
    pub id: TurnID,
    pub turn_type: TurnType,
    pub geom: PolyLine,

Expand description

A Turn leads from the end of one Lane to the start of another. (Except for pedestrians; sidewalks are bidirectional.)

Implementations§

source§

impl Turn

source

pub fn conflicts_with(&self, other: &Turn) -> bool

source

pub fn angle(&self) -> Angle

source

pub fn between_sidewalks(&self) -> bool

source

pub fn penalty( &self, constraints: PathConstraints, map: &Map ) -> (usize, usize, usize)

Penalties for (lane types, lane-changing, slow lane). The penalty may depend on the vehicle performing the turn. Lower means preferable.

source

pub fn is_crossing_arterial_intersection(&self, map: &Map) -> bool

source

pub(crate) fn permitted_by_lane(&self, map: &Map) -> bool

Is this turn legal, according to turn lane tagging?

source

pub(crate) fn permitted_by_road(&self, i: &Intersection, map: &Map) -> bool

Is this turn legal, according to turn restrictions defined between road segments?

source

pub fn crosswalk_over_road(&self, map: &Map) -> Option<DirectedRoadID>

If this turn is a crosswalk over a single road, return that road and which end of the road is crossed.

source

pub fn crosswalk_line(&self) -> Option<Line>

Only appropriat for pedestrian crossings. The geometry of crosswalks will first cross part of a sidewalk corner, then actually enter the road. Extract the piece that’s in the road.

impl<'de> Deserialize<'de> for Turn

source§

source§

impl PartialEq for Turn

source§

fn eq(&self, other: &Turn) -> bool

1.0.0 · source§

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
