Not my first time implementing Raft. I wrote about another implementation in Go I did. But you don't learn a concept well until you've implemented it a few times. And I wanted some practice with Rust.

Goals:

• No dependencies beyond the standard library.
• Leader election.
• Log replication.

Non-goals (for now):

• Production use.
• Snapshots and log truncation.
• Cluster membership changes.
