geometry_tile_data.rs

1//! Translated from https://github.com/maplibre/maplibre-native/blob/4add9ea/src/mbgl/tile/geometry_tile_data.cpp
2//! In maplibre-native GeometryTileFeature are traits/classes and there are impls for symbol, fill, line features etc.
3//! The same is true for the data objects which might be backed by geojson
