Fields

polygons_per_cell: Vec<Vec<Polygon>>

Rarely, this might be empty if the area is very small

colors: Vec<Color>

Colors per cell, such that adjacent cells are colored differently

boundary_polygon: Polygon

Implementations

source

impl RenderCells

source

pub fn new(map: &Map, neighbourhood: &Neighbourhood) -> RenderCells

Partition a neighbourhood’s boundary polygon based on the cells. This discretizes space into a grid, and then extracts a polygon from the raster. The results don’t look perfect, but it’s fast.

source

pub fn draw_colored_areas(&self) -> GeomBatch

Draw cells as areas with different colors. The colors are meaningless, but the same color won’t be shared between adjacent cells.

source

pub fn draw_island_outlines(&self) -> GeomBatch

Draw the boundary between cells as a thick outline. It’s meant to look like the neighbourhood is split into disconnected islands.

source

pub fn to_multipolygons(&self) -> Vec<MultiPolygon>ⓘNotable traits for Vec<u8, A>`impl<A> Write for Vec<u8, A> where A: Allocator,`

Per cell, convert all polygons to a geo::MultiPolygon. Leave the coordinate system as map-space.

T: Any,

fn into_any(self: Box<T, Global>) -> Box<dyn Any + 'static, Global>

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. Read more

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. Read more

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. Read more
