Ruaft: Raft implemented in Rust

Ruaft is a Rust version of the Raft consensus protocol. The name is clearly made up.

At the moment it is a gigantic class lives in a single file. It exposes 4 APIs, to create a Raft instance (new()), start a new contract (start()), get the current status (get_status()) and shut it down (kill()). When a consensus is reached, it notifies the clients via an apply_command callback. It saves its internal state to local disk via a persister, which is supplied at creation.

There are also two half-APIs: process_append_entries() and process_request_vote(), serving requests from other Raft instances of the same setup.

The implementation is thoroughly tested. I copied the tests from an obvious source. To avoid being indexed by a search engine, I will not name the source. The testing framework from the same source is also translated from the original Go version. The code can be found at labrpc repo.

Next steps

• Split into multiple files
• Add public documentation
• Add a proper RPC interface to all public methods
• Benchmarks
