I love modules, because they are adorable!!
Native Maps for Web, Mobile and Linux
A map rendering library written in Rust.
This project is in a proof-of-concept state. The proof of concept is done except for text rendering.
The Rust ecosystem is suited very well for this project.
In the future this project could be adopted and supported by Maplibre to implement a
next-gen mapping solution.
mapr is a portable and performant vector maps renderer. We aim to support the web, mobile and desktop applications. This
is achieved by the novel WebGPU specification. Plenty of native implementations are
already implementing this specification. On the web it is implemented by Firefox, Chrome and Safari. There are also
standalone implementations which directly use Vulkan, OpenGL or Metal as a backend. Those backends allow mapr to run on
mobile and desktop applications.
Rust is used as a Lingua-franka on all platforms. This is made possible by WebAssembly which allows us to use Rust for
The goal of mapr is to render maps in order to visualize data. Right now the goal of mapr is not to replace existing
vector map renderers like Google Maps, Apple Maps or MapLibre. The current implementation serves as a proof-of-concept
of the used technology stack. It is unclear whether the high-performance requirements of rendering maps using vector
graphics are achievable using the current stack.

Building & Running
Now, to clone the project:
git clone –recursive firstname.lastname@example.org/maxammann/mapr
and then build it for running on a desktop:
After that you can run it on your desktop:
cargo run –example desktop —
More information about building for different platforms can be
Note for Mac: Before opening the XCode project, you need to build manually using the following command:
cargo build –target aarch64-apple-darwin –lib
After that, open the XCode project and run it.
(XCode seems to set some environment variables which cause problems with the build directly within XCode)
Install rustup because this is the recommended way of setting up Rust toolchains.
The toolchain will be automatically downloaded when building this project.
See ./rust-toolchain.toml for more details about the toolchain.
This generates the documentation for this crate and opens the browser. This also includes the documentation of every
