Struct map_model::DiagonalFilter

    pub r1: RoadID,

Expand description

A diagonal filter exists in an intersection. It’s defined by two roads (the order is arbitrary). When all of the intersection’s roads are sorted in clockwise order, this pair of roads splits the ordering into two groups. Turns in each group are still possible, but not across groups.

Be careful with PartialEq – see approx_eq.

Implementations§

source§

impl DiagonalFilter

source

pub fn cycle_through_alternatives( map: &Map, i: IntersectionID, filter_type: FilterType ) -> Vec<EditCmd>

The caller must call this in a before_edit / redraw_all_icons “transaction.”

source

fn new( map: &Map, i: IntersectionID, r1: RoadID, r2: RoadID, filter_type: FilterType ) -> DiagonalFilter

source

pub fn geometry(&self, map: &Map) -> Line

Physically where is the filter placed?

source

pub fn allows_turn(&self, from: RoadID, to: RoadID) -> bool

source

pub fn avoid_movements_between_roads(&self) -> Vec<(RoadID, RoadID)>

source

fn approx_eq(&self, other: &DiagonalFilter) -> bool
