## What it is
A Rust crate implementing the Raft distributed consensus protocol on top of the Tokio async runtime. It provides a reactive, fully async Raft node with pluggable storage and networking traits, pipelined log replication, and dynamic cluster membership support.

## Use cases
- build a replicated distributed data store in Rust
- add Raft consensus to a distributed database or KV store
- implement leader election and log replication over Tokio
- manage dynamic cluster membership changes in a distributed system
- replicate state machine logs across nodes asynchronously

## When to choose
- you are building a distributed storage system in Rust with Tokio
- you need a reactive, event-driven Raft implementation with pluggable storage and network backends
- you need dynamic membership changes, snapshots, and log compaction

## When to avoid
- you need a battle-tested, actively maintained Raft library — the project has seen limited activity since 2023
- you are not using Rust or the Tokio async ecosystem
- you need a ready-made distributed database rather than a consensus library to embed
