Struct map_model::DiagonalFilter

pub struct DiagonalFilter {
    pub i: IntersectionID,
    pub r1: RoadID,
    pub r2: RoadID,
    pub filter_type: FilterType,
    pub group1: BTreeSet<RoadID>,
    pub group2: BTreeSet<RoadID>,
}

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.

Fields

i: IntersectionID

r1: RoadID

r2: RoadID

filter_type: FilterType

group1: BTreeSet<RoadID>

group2: BTreeSet<RoadID>

Implementations

impl DiagonalFilter

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.”

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

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

Physically where is the filter placed?

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

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

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

Trait Implementations

impl Clone for DiagonalFilter

fn clone(&self) -> DiagonalFilter

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DiagonalFilter

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DiagonalFilter

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for DiagonalFilter

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

This method tests for self and other values to be equal, and is used by ==.

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.

impl Serialize for DiagonalFilter

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
