Struct GeoJsonSource 

pub struct GeoJsonSource {
    pub data: FeatureCollection,
    /* private fields */
}

In-memory vector feature source with optional point clustering.

Fields

data: FeatureCollection

Features exposed by the source.

Implementations

impl GeoJsonSource

pub fn new(data: FeatureCollection) -> Self

Create a new in-memory vector source.

pub fn with_clustering(self, options: ClusterOptions) -> Self

Enable point clustering on this source.

Builds the cluster index immediately from the current data. Layers that reference this source will receive clustered features at the appropriate zoom level instead of the raw point data.

pub fn is_clustered(&self) -> bool

Returns true if this source has clustering enabled.

pub fn features_at_zoom(&self, zoom: u8) -> Cow<'_, FeatureCollection>

Resolve features for a given zoom level.

If clustering is enabled, returns zoom-appropriate clustered features. Otherwise returns a borrowed reference to the raw data.

Trait Implementations

impl Clone for GeoJsonSource

fn clone(&self) -> GeoJsonSource

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GeoJsonSource

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
