Struct VectorTileData 

pub struct VectorTileData {
    pub layers: HashMap<String, FeatureCollection>,
}

Decoded vector tile payload: per-source-layer feature collections.

This is the output of the MVT/PBF decoder. Each key in layers corresponds to a source layer name inside the vector tile, and the value is the decoded feature collection for that layer.

Fields

layers: HashMap<String, FeatureCollection>

Per-source-layer feature collections.

Implementations

impl VectorTileData

pub fn feature_count(&self) -> usize

Return the total number of features across all layers.

pub fn layer_count(&self) -> usize

Return the number of source layers.

pub fn is_empty(&self) -> bool

Return true if all layers are empty.

pub fn layer(&self, name: &str) -> Option<&FeatureCollection>

Look up a source layer by name.

pub fn layer_names(&self) -> Vec<&str>

Return the names of all source layers.

pub fn approx_byte_len(&self) -> usize

Approximate byte size for cache accounting.

This counts coordinate data only (16 bytes per GeoCoord).
