About

C++-to-Rust bindings for Valhalla Routing Engine, powered by cxx.

valhalla-rs provides drop-in infrastructure (cargo add valhalla and you're ready) for utility projects that need to access Valhalla's road graph data, expose additional Valhalla functionality, or benefit from calling Valhalla's routing engine in-process.

valhalla-debug demonstrates this use case.

Features:

  • Tile access: Read Valhalla tiles and access road graph edges (DirectedEdge, EdgeInfo) and nodes (NodeInfo) - see tiles_tests for examples
  • Actor API: Route building and routing operations similar to Valhalla's Python bindings - see actor_tests for examples
  • Live traffic: Write traffic information directly to memory-mapped traffic.tar

Usage

Run cargo add valhalla or add this to your Cargo.toml:

[dependencies]
valhalla = "0.6"

Dependencies

Since Valhalla heavily relies on system libraries, you need to install the following dependencies to build this project:

sudo apt-get update && sudo apt-get install -y --no-install-recommends clang pkg-config build-essential cmake libboost-dev liblz4-dev libprotobuf-dev protobuf-compiler zlib1g-dev

See the Dockerfile for a complete reference setup, or the Valhalla documentation for other platforms.
