Rust WPILib

rust-wpilib is an equivalent to WPILib, rewritten in Rust. The goal of this project is to create a lightweight alternative to WPILib for FIRST Robotics Competition teams who would prefer to use the language for its safety guarantees.

Getting started

This repository is designed to be compiled for a RoboRIO, the processor used in the FIRST Robotics Competition. To cross compile for RoboRIO, you have to do a few things:

1. Install Rustup to help manage Rust toolchains.
2. Run rustup target add arm-unknown-linux-gnueabi to install the Rust stdlib for ARM-based Linux.
3. Install some variant of arm-linux-gnueabi-gcc. For example, the official FRC toolchain (arm-frc-linux-gnueabi-gcc) is available here, or you can install a generic toolchain with your package manager of choice (sudo apt-get install gcc-arm-linux-gnueabi on Ubuntu).

4. Edit your ~/.cargo/config file with the following information:

   [target.arm-unknown-linux-gnueabi]
   linker = "<path-to-arm-linux-gnueabi-gcc>"

Using this library as a dependency:

This library is not currently published on crates.io. However, you can directly declare it as a dependency:

Cargo.toml:

[dependencies]
wpilib = { git = "https://github.com/robotrs/rust-wpilib" }

Building

You can build your own project for the RoboRIO by passing --target=arm-unknown-linux-gnueabi when building.

To build this library on its own, just run cargo build --target=arm-unknown-linux-gnueabi. To make sure that everything links properly, you may also want to run cargo build --example test_robot --target=arm-unknown-linux-gnueabi.
