Struct Snapper

Help

struct Snapper {
    roads_incoming: HashMap<DirectedRoadID, Pt2D>,
    roads_outgoing: HashMap<DirectedRoadID, Pt2D>,
    movements: BTreeMap<MovementID, Movement>,
}

Expand description

Snaps a line to a vehicle movement across an intersection. It uses movement endpoints and a hint about turn type to match.

OSM IDs aren’t used to snap, because GMNS and A/B Street may disagree about where a road segment begins/ends. This could happen from OSM IDs changing over time or from different rules about importing things like service roads.

Implementations§

impl Snapper

Source

fn new(map: &Map, i: IntersectionID) -> Result<Snapper>

Source

fn get_mvmnt( &self, pair: (Pt2D, Pt2D), code: &str, map: &Map, ) -> Result<MovementID>

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

impl<T> Downcast for T
where T: Any,

§

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

§

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.

§

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

§

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

§

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Send + Sync>

Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait.
