An implementation of "Google Projection" (WebMercator) in Rust. It projects lat/long coordinates into screenspace pixels and back again for use when building a tileserver that works with Google Maps, among others.
It's a port of Go code found in the fawick/go-mapnik project on GitHub, in turn implemented from OpenStreetMap generate_tiles.py.
Import the googleprojection crate and use the public functions from_ll_to_pixel and from_pixel_to_ll on it. You can also use the Mercator struct if you need custom tile sizes. See API documentation and tests for more details.
