FlexStack(R) Community Edition — Rust

Rust License

Short description

FlexStack(R) is a software library implementing the ETSI C-ITS protocol stack. Its aim is to facilitate and accelerate the development and integration of software applications on vehicles, vulnerable road users (VRU), and roadside infrastructure that requires the exchange of V2X messages (compliant with ETSI standards) with other actors of the V2X ecosystem.

This repository contains the Rust implementation of the FlexStack library, providing a high-performance, memory-safe ETSI C-ITS GeoNetworking (EN 302 636-4-1) and BTP (EN 302 636-5-1) protocol stack. It supports CAM, DENM, and VAM message encoding/decoding and transmission.

Documentation

Extensive documentation is available at https://flexstack.eu.

Library API documentation can be generated locally by running:

cargo doc --open

Pre-requisites

Supported Operating Systems

This library can run on any system that supports Rust 1.75 or higher, including Linux, macOS, and Windows. Raw link-layer access (via pnet) may require elevated privileges or specific capabilities (e.g. CAP_NET_RAW) on Linux.

Cross-compilation for embedded or non-x86 targets (e.g. aarch64-unknown-linux-gnu) is fully supported.

Dependencies

All dependencies are managed by Cargo and declared in Cargo.toml:

Crate Version Purpose
pnet 0.34 Raw link-layer packet I/O
rand 0.8 Random number generation
libc 0.2 POSIX system bindings
rasn 0.26 ASN.1 encoding/decoding (for CAM, DENM, VAM)

Build tools

Requires a stable Rust toolchain. Install via rustup:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

To build the library:

cargo build --release

To build and run examples:

cargo run --example cam_sender_receiver
cargo run --example denm_sender_receiver
cargo run --example vam_sender_receiver

Cross-compilation for aarch64

  1. Add the target: 
    rustup target add aarch64-unknown-linux-gnu
  2. Install the cross-linker (Debian/Ubuntu): 
    sudo apt install gcc-aarch64-linux-gnu
  3. Configure the linker in .cargo/config.toml: 
    [target.aarch64-unknown-linux-gnu]
linker = "aarch64-linux-gnu-gcc"
  4. Build: 
    cargo build --release --target aarch64-unknown-linux-gnu

Alternatively, use cross for a Docker-based, zero-configuration cross-compilation:

cargo install cross
cross build --release --target aarch64-unknown-linux-gnu

Known Limitations

  • Raw link-layer reception and transmission (via pnet) requires CAP_NET_RAW privileges or running as root on Linux.
  • The ASN.1 codec (rasn) may not support all ETSI C-ITS optional extensions. Messages have been tested for interoperability with existing commercial implementations.

Installation

Add the library to your Cargo.toml:

[dependencies]
rustflexstack = { git = "https://github.com/Fundacio-i2CAT/rustflexstack" }
