Struct ltn::ModalFilters

pub struct ModalFilters {
    pub roads: BTreeMap<RoadID, Distance>,
    pub intersections: BTreeMap<IntersectionID, DiagonalFilter>,
    pub previous_version: Box<Option<ModalFilters>>,
    pub change_key: usize,
}

Stored in App session state. Before making any changes, call before_edit.

Fields

roads: BTreeMap<RoadID, Distance>

For filters placed along a road, where is the filter located?

intersections: BTreeMap<IntersectionID, DiagonalFilter>

previous_version: Box<Option<ModalFilters>>

Edit history is preserved recursively

change_key: usize

This changes every time an edit occurs

Implementations

impl ModalFilters

pub fn before_edit(&mut self)

Call before making any changes to preserve edit history

pub fn cancel_empty_edit(&mut self)

If it’s possible no edits were made, undo the previous call to before_edit and collapse the redundant piece of history.

pub fn update_routing_params(&self, params: &mut RoutingParams)

Modify RoutingParams to respect these modal filters

pub fn allows_turn(&self, t: TurnID) -> bool

pub fn draw(&self, ctx: &EventCtx<'_>, map: &Map) -> Toggle3Zoomed

Draw all modal filters
