Struct TileWorker 

pub struct TileWorker {
    pub id: usize,
    pub minzoom: u8,
    pub maxzoom: u8,
    pub vector_store: MultiMap<S2CellId, MVectorFeature>,
    pub cluster_stores: BTreeMap<String, PointCluster<MValue>>,
    pub raster_stores: BTreeMap<String, PointGrid<RGBA>>,
    pub grid_stores: BTreeMap<String, PointGrid<f64>>,
    /* private fields */
}

Convert a vector feature to a collection of tiles and store each tile feature

Fields

id: usize

Id of the worker (useful for threads)

minzoom: u8

total minzoom

maxzoom: u8

total maxzoom

vector_store: MultiMap<S2CellId, MVectorFeature>

Store Vector Features whose key are Tile IDs.

cluster_stores: BTreeMap<String, PointCluster<MValue>>

Unique store for each layer that describes itself as a cluster source

raster_stores: BTreeMap<String, PointGrid<RGBA>>

Unique store for each layer that describes itself as a raster source

grid_stores: BTreeMap<String, PointGrid<f64>>

Unique store for each layer that describes itself as a grid source

Implementations

impl TileWorker

pub fn new(id: usize, build_guide: BuildGuide) -> Self

Create a new TileWorker

pub fn sort(&mut self)

Iterate through all the stores and sort/cluster as needed

pub fn store_feature<M: Clone + HasLayer, P: MValueCompatible, D: MValueCompatible>( &mut self, feature: VectorFeature<M, P, D>, source_name: String, on_layer_feature: Option<&Vec<LayerHandler<M, P, D>>>, )

Store a feature to the appropriate store

Parameters

• feature: The feature to store
• source_name: The name of the source to store the feature in
• on_layer_feature: An optional handler to update or filter the feature

pub fn store_vector_feature( &mut self, feature: MVectorFeature, layer: VectorLayerGuide, )
