Struct Tile

pub struct Tile<M> {
    pub id: CellId,
    pub layers: BTreeMap<String, Layer<M>>,
    pub transformed: bool,
}

Tile Class to contain the tile information for splitting or simplifying

Fields

id: CellId

the tile id

layers: BTreeMap<String, Layer<M>>

the tile’s layers

transformed: bool

whether the tile feature geometry has been transformed

Implementations

impl<M: HasLayer + Clone> Tile<M>

pub fn new(id: CellId) -> Self

Create a new Tile

pub fn is_empty(&self) -> bool

Returns true if the tile is empty of features

pub fn add_feature(&mut self, feature: VectorFeature<M>, layer: Option<String>)

Add a feature to the tile

pub fn transform(&mut self, tolerance: f64, maxzoom: Option<u8>)

Simplify the geometry to have a tolerance which will be relative to the tile’s zoom level. NOTE: This should be called after the tile has been split into children if that functionality is needed.

impl<M: HasLayer + Clone> Tile<M>

pub fn split(&mut self, buffer: Option<f64>) -> TileChildren<M>

split tile into 4 children
