## Overview

This repository contains the source code of *Rust Barefoot Runtime (RBFRT): Fast Runtime Control for the Intel Tofino* ([preprint paper](https://arxiv.org/abs/2501.17271)).

The RBFRT is a Rust-based control plane library.
It provides a fast and memory-safe interface to configure the Intel Tofino.
It uses gRPC and the official Protobuf definitions of the [Open-Tofino](https://github.com/barefootnetworks/Open-Tofino) GitHub repository.

## Features

- **BFRuntime gRPC Interface** - High-level table, register, and digest operations
- **Thrift PD API Support** (optional) - Low-level platform-dependent operations
  - Port MTU configuration
  - Traffic Manager (TM) APIs
  - Multicast and pipeline management

To enable the optional Thrift PD API support in your project, activate the `thrift-support` feature:

```toml
  [dependencies]
  rbfrt = { version = "0.1.11", features = ["thrift-support"] }

## Documentation

The documentation of this crate is deployed as a [GitHub page](https://uni-tue-kn.github.io/rbfrt/rbfrt/).
