C-Rust Program Pairs

This repository contains a list of C-Rust program pairs. Each pair consists of a C program and a Rust program with similar functionality. The metadata/ directory lists the program pairs. Often the Rust program was translated from or inspired by the C program. Program pairs only include the source code without any dependencies, so they cannot be compiled.

Here is the directory structure for the downloaded cat program pair:

.
└── program_pairs/
    └── cat/
        ├── c-program/
        │   └── cat.c
        └── rust-program/
            └── cat.rs

Prerequisites

You need the SSL development library. On Ubuntu, run:

sudo apt-get install -y pkg-config libssl-dev

Usage

To download all available program pairs into the program_pairs/ directory:

cargo run

To download a small subset of available program pairs:

cargo run demo

To delete program_pairs/ and repository_clones/:

cargo run delete

Terminology

• Program: Code that compiles to a single executable.
• Pair: A pair of C and Rust programs with similar functionality.
• Project: A repository with C or Rust code. A project contains one or more programs.
• Metadata: Information about one or more pairs.

Resources

• Awesome Rust: Contains a list of awesome Rust projects - many of which might be translated from C projects.
• JSON Schema Validator: Used to validate JSON schemas.

Possible TODOs

• git pull repositories in the cache to update them.
• Use date or git SHA so repositories downloaded are consistent from run to run.
