EarthWyrm is a Rust library for generating vector tiles in MVT format. It can serve OpenStreetMap or other GIS data.

Layers

GIS data is stored as R-Trees in a rosewood file for each layer. They contain point, linestring or polygon features, with associated tags. The geometry uses Web Mercator projection (EPSG:3857).
