Struct CustomVectorSourceOptions 

pub struct CustomVectorSourceOptions {
    pub fetch_tile: Arc<dyn Fn(&MapHandle, &str, CanonicalTileId) + Send + Sync + 'static>,
    pub cancel_tile: Option<Arc<dyn Fn(&MapHandle, &str, CanonicalTileId) + Send + Sync + 'static>>,
    pub min_zoom: Option<f64>,
    pub max_zoom: Option<f64>,
}

The callbacks and options of a custom vector source.

Zoom levels are whole numbers from 0 to 32.

See mln_custom_vector_source_options in the C API reference.

Fields

fetch_tile: Arc<dyn Fn(&MapHandle, &str, CanonicalTileId) + Send + Sync + 'static>

The callback receives (map, source_id, tile_id).

cancel_tile: Option<Arc<dyn Fn(&MapHandle, &str, CanonicalTileId) + Send + Sync + 'static>>

The callback receives (map, source_id, tile_id).

min_zoom: Option<f64>

max_zoom: Option<f64>
